How to Share Holiday Rentals With Strangers? TOP Coliving Apps and Shared Vacation Airbnbs

We live in Malta, and we have always wondered about the groups of young travelers we see here. Boys and girls alike, six to ten of them, aged somewhere between eighteen and thirty, traveling together and living in apartments.

We kept thinking: where do they know each other from? School, work, university, some club or shared interest? And they always stay in apartments, never in hostels.

Then we learned that many of them are seeing each other for the first time. They had simply met to share accommodation, on a social platform like Reddit or a dedicated accommodation-sharing app. It works like BlaBlaCar — the app that matches drivers with passengers heading the same way so they can split the cost of the journey — except applied to a spare bedroom instead of an empty car seat.

So we decided to explore the concept properly: how it works, the terms, and the best apps.

Is There a BlaBlaCar for Airbnb? The Short Answer

Airbnb solved one side of the travel equation: it made millions of privately owned homes available to travelers. BlaBlaCar solved another: it matched people traveling in the same direction so they could share the cost of a car journey.

Combine the two and the math gets interesting. A four-bedroom villa in Mallorca at €2,000 a week is absurd for one person. Split four ways it’s €500 each — a private bedroom, a kitchen, a terrace and a pool for roughly the price of an ordinary hotel room.

The obvious question is whether there’s an app for finding strangers to share a vacation rental with.

Until recently the honest answer was “not really.” Several platforms connect people who want to travel together, coliving companies sell individual rooms in communal properties, and organized small-group travel has moved much closer to independent travel — but a true “BlaBlaCar for vacation rentals” barely existed.

That has started to change. At least one platform now does precisely this, and the older workarounds are still what most people actually use.

How Sharing an Airbnb With Strangers Would Work

Suppose you want a week in Ibiza and want neither a hostel dorm nor an expensive hotel room. You find a licensed four-bedroom rental at €2,400 for seven nights. Instead of recruiting three friends, a platform would let you post the destination, the dates, the price per person, which bedrooms are private, and preferences: age range, smoking, remote work, quiet or party.

Other verified users request to join. Everyone sees profiles and reviews before agreeing to travel together. Once the group fills, payment is collected and the property is booked.

It’s the accommodation equivalent of filling an empty seat.

SplitStay

Best for: splitting a specific booking with a verified stranger

SplitStay is the closest thing yet to the idea in its pure form, and it describes itself as BlaBlaCar meets Booking.com. It launched in March 2026 out of the Belgian accelerator Start it @KBC.

It came out of Start it @KBC, the Belgian accelerator, and works as a layer on top of the platforms you already use rather than a competing marketplace. You create a verified profile, post the trip you’re taking — destination, dates, preferences such as age range, languages and interests — and the platform suggests compatible co-guests heading to the same place at the same time. You agree who you’re comfortable sharing with, then book the room, apartment or villa independently on Booking.com, Airbnb or elsewhere and split the cost. A platform fee covers the matchmaking.

The early focus has been event travel — festivals, sports tournaments, trade fairs and conferences — where accommodation prices spike and solo attendees are plentiful. That’s a sensible wedge: everyone arrives on the same dates for the same reason, which solves half the matching problem before you start.

JoinMyTrip

Best for: joining a trip somebody else has organized

JoinMyTrip is the most established of the matching platforms. It was founded in Hamburg in 2017 by Niels Mueller-Wickop and Valentin Funk, trading as Travelsation, and remains a small operation — roughly thirty staff, seed-funded, with backing from Matzen Ventures and STS Ventures. The company says around 160,000 travelers have used it, and it has about 28,000 followers on LinkedIn.

Trips are created and hosted by a vetted TripLeader — an experienced traveler or local host, not a professional guide — who arranges the accommodation and itinerary and sets the price. Other travelers, called TripMates, apply to join and secure a place with a 20% deposit, after which the TripLeader confirms them and adds them to a group chat before departure.

Groups are deliberately small, typically three to twelve people, and accommodation is normally included in the price. The important distinction is that you’re joining a trip, not simply buying a spare bedroom in somebody’s rental.

WeRoad

Best for: solo travelers who want an organized social trip

WeRoad is more structured. You pick a destination and a departure date, and the company assembles a small group around a Group Leader — a trained traveler rather than a tour guide, who handles check-ins, transport, activities and the shared budget. Accommodation is included; flights generally are not, by design. A WhatsApp group opens roughly fifteen days before departure.

It removes most of the uncertainty of arranging a property with strangers, at the cost of some independence.

This is the best-capitalized company in the category by a wide margin. WeRoad is backed by Airbnb and raised $58 million in May 2026 to fund expansion into the United States. It works with more than 4,000 group leaders worldwide, and says roughly 60% of its travelers go on to book a second trip — which is the number that matters most in a business built on strangers getting along.

Outsite

Best for: digital nomads and remote workers

Outsite comes at the problem from the property side. Rather than finding strangers and then renting somewhere together, you book a room in accommodation designed around communal living and remote work. The community is a feature of the building rather than something you assemble yourself.

Founded in 2015 by Emmanuel Guisset and headquartered in Santa Cruz, California, it runs an annual membership alongside the nightly rates and operates around 50 locations across Europe, the Americas, Africa and Asia, with a member base the company has put in the thousands. In late 2023 it announced a €300 million real-estate partnership with the funds EXTENDAM, Keys REIM and Stone Capital — the investors buy the buildings, Outsite operates them for a share of revenue, which is how it plans to expand in France, Spain, Italy, Portugal and cities like Berlin and Amsterdam without raising equity against every property.

Cohabs

Best for: longer urban stays

Cohabs sits closer to residential coliving than vacation travel — furnished private bedrooms in shared houses, with the operator managing everything. It suits relocations, longer stays and remote workers rather than a week away.

Founded in Brussels in 2016 by Youri Dauber, Malik Dauber and François Samyn, with interiors by designer Lionel Jadot, Cohabs is unusual in that it owns as well as operates its buildings. It raised €110 million in late 2022 from Ivanhoé Cambridge, Belfius Insurance and the real-estate arm of the Belgian sovereign fund, and reports a portfolio of roughly 2,000 bedrooms across Brussels, Paris, New York, Madrid and Luxembourg, with a stated target of 5,000 bedrooms across eleven cities. Houses typically run 20 to 25 rooms, and rent is all-inclusive.

Worldpackers

Best for: budget travelers willing to trade time or skills

Worldpackers runs a different model entirely: travelers exchange work or skills for accommodation with hostels, guesthouses, NGOs and other projects. It isn’t Airbnb sharing, but it belongs to the same move away from one traveler, one hotel room.

It is also, by membership, the largest platform here. Founded in São Paulo in 2013 by Ricardo Lima, João Machini de Miranda and Eric Faria, it says its community has passed 8.3 million travelers, with hosts in more than 140 countries. Travelers pay an annual membership rather than per stay, and its iOS app carries one of the better ratings in travel at 4.9 stars.

What About Airbnb Itself?

Airbnb accommodates groups perfectly well, and has since 2017 offered a group payment feature that lets one booker split the cost across as many as sixteen people. What it isn’t is a stranger-matching service — you generally arrive with your group already assembled. That leaves room for a matching layer between solo travelers and vacation-rental platforms. If you’re booking one yourself, our guide to booking a short Airbnb stay without headaches covers the practical side, and there are ways to cut the cost before you split it.

Sharing Apartments in Malta: How It Already Works

Malta is the clearest real-world example we know, because the behavior an app would formalize is visible from any balcony in St Julian’s.

Around St Julian’s, Sliema, Gżira and Swieqi, young visitors routinely rent apartments together instead of booking hotel rooms. For nightlife-oriented travelers the logic is obvious: Paceville concentrates Malta’s clubs and late-night venues into a few compact streets, and a three- or four-bedroom apartment within walking distance functions like a private hostel. Everyone gets more space, the rent divides, and nobody needs a taxi across the island at 4am.

This is exactly where a matching marketplace would change things. Instead of needing four friends with the same week free, one or two travelers could assemble a group of verified people arriving on the same dates.

Malta could plausibly support several distinct matching categories: Paceville nightlife weekends, summer beach holidays, English-language students, diving trips, and longer stays by remote workers.

The Part Nobody Advertises: The 3am Walk Home

There is another side to this, and anyone who lives here knows it.

Paceville empties between three and four in the morning, and the walk home goes straight through residential streets. A group of eight coming back from a night out is not quiet, and they are not going to bed. The noise lands on neighbors and, eventually, on property owners — who deal with the complaints, the wear, the deposits and the letters from the building administrator.

You can see the tension most clearly at a place like Pendergardens, the gated development in St Julian’s. Agents will tell you the blocks don’t permit short lets. In practice, a good number of the apartments are bought and furnished for precisely that purpose, and let out week by week. The same is true in several of the other gated complexes marketed as quiet residential addresses. Malta’s 2026 licensing regime, with its named 24-hour contact for complaints and its requirement to notify the building administrator once a licence is issued, is a direct response to exactly this gap between what a development says it is and what it actually does.

And the hostel option has not gone anywhere. Marco Polo Party Hostel on Ross Street, a few minutes from the clubs, stays busy year-round on the strength of its rooftop bar and free walking tours, with several thousand reviews across the booking platforms and beds among the cheapest on the island. For a lot of solo travelers it remains the more sensible answer — and it absorbs exactly the noise that an apartment block is not designed to.

Malta Short-Let Rules: Licences and Occupancy Limits

Here the rules matter more than they used to, and this is the correction we’d most want a reader to take away.

Malta replaced its accommodation legislation in April 2026 with the Tourism Accommodation Regulations (S.L. 409.24), consolidating several older instruments. Under the new regime, operating or advertising a short-let without a Malta Tourism Authority licence is expressly prohibited, and licences are property-specific.

Two conditions bear directly on group travel:

• Occupancy is capped at two people per bedroom, and ten people per unit — unless the property has independent access from a public road.
• Basement rooms may not be used as bedrooms.

Licensed properties must also display a notice showing the licence number and a 24-hour contact, name a person available around the clock to handle complaints, carry insurance extending to common parts where relevant, and submit a waste management plan.

So the groups of six to ten we’ve been watching for years are, under the current rules, sitting right at the legal ceiling. A group of ten in a licensed unit needs five bedrooms and, in an apartment block without independent street access, is at the maximum the law allows. That is worth knowing before ten people agree to split a three-bedroom flat.

And the obvious point, which no app changes: a shared apartment does not become a party venue because several young travelers rented it. Occupancy limits, house rules, condominium rules and noise regulations all still apply. If you’re after somewhere quieter and more considered, Malta has that too — Casa Bonavita is the opposite end of the same island.

Best Destinations for Shared Vacation Rentals

Mallorca and Ibiza. Large villas and fincas become dramatically more economical divided between travelers.

The Greek islands. Mykonos, Santorini, Crete and Corfu have deep villa markets, and the economics beat several hotel rooms comfortably — as our guide to Mykonos villas with private pools shows.

The Algarve. Villas, surf culture, longer-stay travelers and an established coliving scene.

Madeira. A visible remote-worker ecosystem makes communal accommodation a natural fit.

Tenerife and the Canaries. Warm winters, long stays, and a large supply of apartments and villas.

Malta. St Julian’s, Sliema, Gżira and Swieqi for younger groups, nightlife visitors and language students; longer stays and remote workers as a second segment.

Lisbon and Barcelona. Sharing a large apartment lowers the per-person cost substantially, but both cities are also where short-term-rental rules bite hardest. If style matters as much as the split, our roundup of Europe’s most stylish Airbnbs is a good starting point.

The shared-rental model occupies an unusual middle ground: the private bedroom of a hotel, some of the social atmosphere of a hostel, and the kitchen and living room of an Airbnb.

Advantages of Sharing a Vacation Rental

Better properties for the money. A €1,600 apartment is expensive for one traveler and €400 each for four. Villas throw in pools, terraces and living space that would be costly to replicate across separate hotel rooms.

More privacy than a hostel. Sharing an apartment doesn’t mean sharing a bedroom. Four travelers, four private rooms, shared kitchen and terrace.

Built-in company. Solo travel can be lonely. Housemates offer company for meals and beaches without obliging anyone to spend the whole week together.

Better for longer stays. Kitchens, washing machines and living areas matter more with every extra week, which is much of why coliving works for remote workers.

Risks of Sharing an Airbnb With Strangers

Compatibility. Rental companions share a week, not a two-hour car journey. Matching would need to account for smoking, alcohol, sleep schedules, parties, remote work, cleanliness, language and whether people actually want to socialize.

Safety. A serious platform needs identity verification, reviews, secure messaging, reporting and fraud checks. JoinMyTrip, for its part, runs background checks on TripLeaders and verifies travelers.

Cancellations. If four people commit to a €2,000 villa at €500 each and one drops out, someone covers the gap. A viable marketplace needs deposits, clear cancellation terms and ideally a replacement-traveler system.

Damage. Liability gets complicated when the person holding the booking barely knows the other guests.

Different expectations. One person’s remote-work retreat is another’s party house. Paceville illustrates precisely why a listing would need an explicit quiet / social / nightlife setting before anyone matches.

Shared Rental or Hostel: Which Is Better for Solo Travelers?

For short solo trips, hostels are hard to beat. One reservation, and you don’t care whether the other beds sell — if someone cancels, your price doesn’t move.

A place like Marco Polo in Paceville exists precisely for this: cheap, social, purpose-built for noise, and staffed by people who expect a 4am return. An apartment block is none of those things.

Shared rentals get interesting for people who’ve aged out of dormitories but still want company: four travelers in their thirties spending ten days in Tenerife, or several people meeting in Malta for a weekend around St Julian’s. The strongest audience is probably older solo travelers, digital nomads, remote workers, and sociable travelers who want company without giving up a private bedroom.

Is Sharing a Vacation Rental With Strangers Legal in Europe?

There is no single European answer, and the important distinction is not whether travelers may share a property. It’s whether the property itself is legally permitted to operate as short-term accommodation, and how many people it may host.

The EU layer. Regulation (EU) 2024/1028 applies from 20 May 2026. It harmonizes how short-term rental data is collected and shared: platforms must collect and verify host registration numbers, display them, and report activity data to national authorities through a single digital entry point. What it does not do is impose EU-wide night caps, licensing rules or zoning restrictions — national, regional and municipal rules still govern all of that. It’s enforcement infrastructure, not a rulebook.

Amsterdam requires both a registration number and an annual holiday-rental permit, and the host must be the main resident. The cap is 30 nights per calendar year, reduced to 15 nights in parts of Centrum and De Pijp since 1 April 2026. Critically for this article: a maximum of four people at a time, and every rental must be reported to the city in advance. Details are on the City of Amsterdam’s own page. A group of six splitting an Amsterdam apartment is not a gray area — it’s over the limit.

Paris caps short-term letting of a principal residence at 90 nights a year, down from the national default of 120, using powers granted to communes by the loi Le Meur. Registration is mandatory and the number must appear on every listing. Lyon, Marseille, Bordeaux and Nice have adopted the lower cap too.

Lisbon operates its Alojamento Local registration framework, with restrictions concentrated in particular areas.

Malta requires an MTA licence, with the two-per-bedroom and ten-per-unit occupancy caps described above.

Four travelers agreeing to divide a bill does not override a property’s licence conditions, maximum occupancy, building rules or local restrictions.

Introducing Travelers vs Selling Accommodation: The Legal Line

There’s a meaningful regulatory difference between introducing compatible travelers and selling them accommodation.

Model A: an app introduces four travelers going to Malta from September 10–17. They form a group and independently make a legitimate booking.

Model B: the app advertises four places at €500 each, collects €2,000 and handles the accommodation transaction itself.

The second creates considerably greater payment, consumer-protection, accommodation and liability obligations — and under the 2026 EU regime, a platform facilitating short-term rentals carries registration-verification and reporting duties of its own. Anyone building this would need specialist advice in every market they operate in.

What the Ideal Airbnb-Sharing App Would Look Like

A traveler enters:

• Destination: Malta
• Area: St Julian’s / Sliema
• Dates: July 10–14
• Budget: €300–€500
• Room: private
• Age: 25–35
• Trip style: nightlife / beaches
• Group size: 4
• Smoking: no
• Paceville nights: yes
• Apartment parties: no

The platform matches compatible travelers first. Only then does the group choose an eligible, licensed property together — with the occupancy cap visible before anyone commits. Profiles and previous-trip reviews build trust the way BlaBlaCar’s do between drivers and passengers, and a replacement system reopens a bedroom to other verified travelers when someone drops out.

How Much Does It Cost to Split a Villa Four Ways?

An illustrative seven-night trip:

• Four hotel rooms × €150 × 7 nights = €4,200
• Four hostel beds × €45 × 7 nights = €1,260
• Four-bedroom villa = €2,000, or €500 each, before fees and taxes

Substantially cheaper than the hotels, more expensive than the hostel, with far more private space than a dormitory. The economics work best where large properties are cheap per bedroom and hotel rooms are expensive — and they improve further if you’re already hunting discount codes on the booking platforms.

So, Is There a BlaBlaCar for Airbnb Yet?

Closer than it was a year ago.

SplitStay is the first platform we’ve found that does the thing exactly — match verified strangers to split one booking — though it’s new, and its early centre of gravity is event travel rather than a week in a villa. JoinMyTrip comes at it from the traveler-matching side. WeRoad solves it through organized group travel. Outsite and the coliving operators solve it from the property side. Worldpackers uses exchange. Airbnb handles group reservations but doesn’t find strangers to fill spare bedrooms.

That leaves a real gap. Millions of people travel alone, and countless rentals sit with two, three or four bedrooms that make no sense for one traveler.

Malta makes it easy to picture, because the end state already exists — the groups are already there, already in the apartments, already walking to Paceville. What’s missing isn’t the behavior. It’s a safe way for people who don’t know each other to form those groups before booking, inside rules that now count heads per bedroom.

The missing product may not be another accommodation marketplace at all. It could be a marketplace for the empty bedrooms inside group bookings — assuming somebody solves trust, compatibility, cancellations, payments, insurance and local regulation, which is the hard part and always was.
