By LOCALS Insider editorial — Alex visited Aman Nai Lert Bangkok at the property’s invitation, organized by Descartes, a private luxury travel concierge service. Photos are exclusive to LOCALS Insider.
The first thing you walk into at Aman Nai Lert Bangkok — once the elevator has taken you nine floors up from the ground-floor entrance — is this: a long, mirror-still reflecting pool lined with floating bamboo-mesh lanterns, hanging woven panels backlit in warm light, and the Bangkok skyline framed through floor-to-ceiling windows on either side. The whole arrival sequence is designed by Jean-Michel Gathy of Denniston, and the references are deliberate: the woven panels echo the textiles inside the Nai Lert Park Heritage Home next door; the floating lanterns echo loi krathong; the dark water echoes the rice paddies on the ancestral land that became Bangkok. None of it shouts. All of it sets the tone.
A new Aman in the middle of old Bangkok
Aman has been part of Thailand’s luxury story since 1988, when the brand essentially invented the modern resort category with Amanpuri in Phuket. Almost four decades later, in April 2025, the group finally planted its flag in the capital with Aman Nai Lert Bangkok — only its third urban Aman in the world, after Tokyo and New York.
The property sits on one of the most historically loaded plots of land in the city. To understand why this matters, you have to know about the man whose name is on the door.
Who was Nai Lert
Lert Sreshthaputra, known to Bangkok as Nai Lert (“Mr. Lert”), was born in 1872 and became the city’s first great modern entrepreneur. He built Thailand’s first ice factory — the closest thing to a refrigerator the country had ever seen at the time, and a small revolution in a tropical capital where keeping anything cold was previously impossible.
From his ice plant he expanded into a walk-in freezer and started importing European cheese, sausages, ham, and whiskey for the new Bangkok elite. He brought bottled lemonade from Singapore.
He imported the first motor vehicles from Europe and the US. He built the tallest commercial building in Bangkok in 1927. He started the city’s first public bus service — the famous “white buses” that ran from Pratunam to Si Phraya and lasted almost 70 years. He even built ships, including teak warships commissioned by Denmark. King Rama VI bestowed on him the title of “Beloved Millionaire.”
In 1915, Nai Lert acquired the land that became his family home — and Bangkok’s first Western-style public park, predating Lumpini. The teak heritage house, Nai Lert Park Heritage Home, is still standing on the property and is one of the most beautiful small museums in central Bangkok. Open to visitors by guided tour, it traces the family’s story across three generations and is genuinely one of the city’s underrated cultural visits.
This is one of Nai Lert’s original imported automobiles — bearing the family name on the plate — kept in working condition at the Heritage Home next to the hotel. He was the first person to bring motor vehicles to Bangkok at the turn of the 20th century. Seeing the car parked under a low Thai-roofed carport with the towers of modern Bangkok rising behind it is, in a single frame, the entire story of what this family did to the city.
What was on this site before
The plot has had two earlier hotel lives. The Nai Lert family opened the original property here in the 1980s as the Hilton International Bangkok at Lert Park. After Hilton’s 20-year management contract ended in 2003, it became Swissôtel Nai Lert Park, a low-rise five-story hotel surrounded by eight acres of tropical garden. The Swissôtel closed in the late 2010s, and the family redeveloped a portion of the parcel as a 36-story tower in partnership with Aman. The hotel occupies floors 1 through 19; the upper floors house 39 Aman-branded private residences.
The Heritage Home and the gardens remain intact. The land’s continuity — from 1915 family home to public park to Hilton to Swissôtel to Aman, all under the same family — is something you don’t get at any other luxury hotel in Bangkok.
The arrival: water as a welcome
The Aman approach to small details starts immediately. The branded mineralized water — served from a frosted glass bottle with the property’s signature low-contrast typography — appears in the suite, in the spa wet zone, in the treatment rooms, beside the gym. Aman doesn’t pour Evian or San Pellegrino. The water is filtered and remineralized on the property and bottled in glass that is collected and reused, which is one of the brand’s small sustainability moves.
It’s also the first signal of what the whole stay feels like. Nothing is loud. Nothing is logoed in the way most luxury hotels insist on. The brand is whispered, not shouted.
The journey to your suite: every floor has an exclusively designed lobby
This is the detail most hotel reviews miss, and the one that genuinely sets the property apart. Every guest floor at Aman Nai Lert Bangkok has its own dramatic double-height lobby — not a corridor with carpet and signage, but a full architectural moment.
The elevator opens onto a long black reflecting pool with a single hand-carved white stone boulder at one end, vertical lantern pillars rising out of the water, and walls finished in rough-cut stone panels that catch every flicker of light. The void rises through two floors, and your suite door is one of the discreet entrances cut into the back wall. You can see two of them in this shot, with another floor’s lobby visible above through the open atrium.
It’s the kind of architectural gesture most luxury hotels skip — the per-floor lobby is usually an afterthought even at five-star properties. Here it’s treated as part of the arrival ritual: you don’t just go to your room, you walk through a small museum-quality space every single time you come or go from your suite.
The Corner Suite
Aman Nai Lert Bangkok has only 52 suites in total — the smallest of which is over 94 square meters (about 1,010 sq ft). There are no standard rooms. The categories are:
- Deluxe Suite — 94-98 sq m (1,010-1,055 sq ft), north-facing city views
- Premier Suite — 94-99 sq m (1,010-1,065 sq ft), south-facing over Nai Lert Park
- Corner Suite — 92 sq m (990 sq ft), southwest corner with sunset views over the park
- Premier Corner Suite — 92 sq m (990 sq ft) with 270-degree views, the largest pure-suite category
- Terrace Suite — with a private outdoor terrace
- Aman Suite — the entire 18th floor, 566 sq m (6,090 sq ft) — or 713 sq m (7,675 sq ft) in the three-bedroom configuration, with cinema, formal dining room for 12, and a wraparound terrace
I was shown a Corner Suite, the category positioned at the southwest corner of the building between floors 11 and 17. Two full-height window walls meet at the corner; one looks down across Nai Lert Park’s tree canopy, the other faces the sunset side of the city. There’s a window seat built into the corner where the glass meets.
The silent suite layout is essentially one large open volume of 92 square meters (990 sq ft), broken into zones by the furniture rather than by walls. From the bed you look directly out across the city. The desk faces one window wall; the sofa runs along the other. A round dark-wood table in the middle is set up for in-room dining or quiet afternoon work. The fabrics are all in the same restrained palette of warm grays and beige; the floor is wide-plank oak; the only color comes from a single bowl of seasonal Thai fruit and a small ceramic vase of fresh-cut foliage that the housekeeping team refreshes daily.
The bathroom is almost the same square footage as the bedroom. The hero piece is a deep, round soaking tub in dark stone — the kind of bathtub you would actually use rather than just photograph — set against the same floor-to-ceiling windows that run through the rest of the suite. There’s a separate rain shower, a long double vanity, and the same muted travertine-and-wood palette that Jean-Michel Gathy of Denniston used through the whole property.
The tub is the photograph you’ve probably seen on Aman’s own materials — a sculptural circle, deep enough that the water comes up to your shoulders when you sit, with matte black floor-standing taps. It’s set right against the window, which is the part the photos never quite capture: you’re soaking with a wide-open view of central Bangkok. At night, with the city lit up and the bathroom dimmed, it’s genuinely one of the better baths you can take in this city.
The rain shower sits behind a low marble divider — no door, no glass screen, the same wet-room approach Aman uses across its newer urban properties. Veined gray marble runs floor-to-ceiling, the fixtures are matte black, and there’s a built-in stone bench for sitting under the rainhead. The amenities — small dark-glass bottles of body wash, shampoo, conditioner, and body cream — are Aman’s custom in-house line, lightly fragranced with a signature blend that you’ll notice repeated throughout the spa downstairs.
A small minibar runs alongside the lounge area, fully stocked with whisky, vodka, and a curated selection of spirits (extra-charge). An iPad at the bedside controls lighting scenes, music, curtains, room temperature, and direct room service ordering — the same Aman in-room control system rolled out across the brand’s newer properties.
The spirits niche above is the kind of detail that tells you who’s directing this hotel. It’s not a row of branded miniatures. It’s a curated three-bottle selection — Japanese whisky (Nikka From the Barrel) sits alongside Saneha, a Thai herbal liqueur made by a small Bangkok producer using local botanicals — displayed in a backlit niche with a textured stone back panel and matching crystal glassware. The blend of Japanese and Thai sensibilities here is everywhere in the design: the teppanyaki and omakase restaurants upstairs, the Aman Club aesthetic, the references in the lobby. This is a Thai hotel that quietly nods to Tokyo throughout.
The little things that matter
What separates Aman from the other top-tier brands in this category is the consistency of small details. Five photographs of small set-pieces from the suite, none of which would qualify as a “feature” anywhere else:
Every cup, saucer, and milk pitcher in the coffee-and-tea drawer is custom-thrown ceramic with a pewter glaze, divided neatly into a pull-out drawer with leather inserts. The drip coffee packets are Aman-branded. The teas are loose-leaf from a small Thai supplier.
The afternoon tea setting arrives unprompted — a single-cup stoneware teapot with a side-handle (Japanese kyusu style), one matching cup, a small bowl of fresh chilled dark cherries, a folded white cloth on a tiny brass tong. No card. No explanation. It just appears, and the cherries are imported from Chile and Washington state during their respective seasons, picked perfectly ripe.
The welcome amenity box on the dressing table — a hand-turned light wood vessel with a metallic finial shaped like a spinning top — holds a small Aman-branded jewelry chain. It’s a goodbye gift, not a sales item. You take it home.
The vanity has a fitted Dyson Airwrap with every attachment, presented in a tailored fabric tray. Every suite has one. It’s not signage — you just open the drawer and find it.
The flowers in the suite — loose, hand-arranged white dendrobium orchids and tall green wild grass stems in a dark ceramic vessel — are changed daily. The arrangement style is deliberately wild, not florist-tight. The orchids are Thai-grown; the grass stems come from a small farm outside Bangkok that supplies several of the city’s top hotels.
The welcome book — a linen-bound, gray-on-gray cloth-cover hardcover with subtle brush-strokes — sits beside an Aman Essentials grooming kit and a small Bang & Olufsen-style portable speaker. The speaker pairs to the in-room iPad. The book itself is a printed object you’d be tempted to take home if it weren’t obviously meant to stay.
This level of detail is everywhere. The slippers, the robes, the bathroom amenities (a custom Aman line, not a third-party brand), the stationery, the in-room scent — all coordinated, all the same restrained palette.
Rates
Rates start from around USD $1,200 per night for entry-level Deluxe Suites and Corner Suites during the European summer (Bangkok’s low season), rising to USD $1,600+ per night during the November-February high season, which is also the most pleasant time to visit Thailand. Premier Corner Suites and Aman Suites command significantly more. Standard Aman inclusions apply: round-trip airport limousine transfer (for Corner Suites and above on one-night stays), fast-track immigration, daily breakfast, and full spa access.
The spa: Bangkok’s unique Banya treatments
The Aman Spa & Wellness Center at Nai Lert Bangkok spans roughly 1,500 square meters (about 16,150 sq ft) across two full floors — the largest urban Aman spa in the world. It includes eight treatment rooms, a 24-hour Technogym fitness center, dedicated movement studios for yoga and Pilates, a hydrotherapy zone, and a private freestanding pavilion called the Banya Spa House.
The 25-meter (82-foot) outdoor pool sits on the 9th floor and is shaded by a century-old Sompong tree that was preserved from the original Nai Lert gardens — I didn’t see this in person because the pool is reserved for in-house guests only, which is the right policy but worth knowing if you’re a visiting spa guest.
What I did see was the public wet zone: a Finnish sauna, a steam room (hammam), a hot plunge basin, a cold plunge basin, and an ice-water bucket positioned between them for the traditional Nordic-style contrast cycle.
Before the wet zone, you pass through this changing-and-relaxation area, which functions as a kind of decompression chamber. Curved woven-rattan privacy screens stand in for traditional locker partitions; the wall on the right is finished with the same cloud-shaped reliefs as the massage room; a tall arrangement of dried wheat heads and white orchids sits in the middle. The whole space is designed to slow you down before you even enter the heat.
The wet zone is smaller than the equivalent at, say, the Mandarin Oriental’s spa or the Four Seasons, but it’s also significantly better designed. Marble walls in a soft gray, low light, a wooden clock on the wall, and a single full-height window that frames the Bangkok skyline. The Finnish sauna has a low-key herbal aroma that the team refreshes during the day; the steam room runs hot enough to actually clear your sinuses without making you feel cooked.
The cold plunge is the one above. The water is dark — that’s deliberate, set into a dark stone basin — and the temperature sits at around 12°C. The view through the window looks straight out onto central Bangkok’s skyline, with a contemporary cultural building catching the light in the foreground. It’s a strange and very Bangkok feeling: you go from a 35°C sauna into a 12°C plunge while watching the city move on the other side of the glass.
The Banya Spa House (and why it’s here in our opinion)
The Banya is the most unusual thing about this spa, and we think that it’s directly inspired by Aman owner Vlad Doronin, who was born in Leningrad in 1962 and has been the chairman of Aman Group since 2014. Russian banya culture is built around the venik — a bundle of oak or birch leaves used by a trained therapist to beat, fan, and slap heated air against the skin in the steam room. It sounds aggressive, and it is, in the best sense: the technique increases circulation, opens pores, releases muscle tension, and produces an effect that’s part deep-tissue massage and part exfoliation.
The freestanding Banya Spa House at Aman Nai Lert Bangkok includes a wood-clad banya sauna, a steam room with a Vichy shower, a couple’s treatment room, hot and cold plunge pools, and a large lounge area. You book the entire pavilion privately.
This is the centerpiece of the banya wet area: a traditional wooden dousing bucket mounted on the wall, banded with steel, with a rope pull on the right. You pull the rope after coming out of the sauna and roughly 15 or more liters of ice-cold water dumps on your head in one go. It’s the part of the Russian banya ritual that nobody who hasn’t done it ever quite believes — and the part that, once you’ve done it, you can’t quite get out of your head afterwards. Aman built one in central Bangkok, which is genuinely one of the most unexpected wellness experiences in the city.
The treatment menu, as published by Aman:
- Banya Spa House Experience (2 hours) — Banya venik treatment, contrast bathing, wellness refreshments, and lounge time. This is the entry option; a venik treatment by itself sits at around USD $1,000.
- Banya Spa House Treatment (+1 hour) — Add a 60-minute body treatment in the Banya Spa House with use of all facilities (sauna, steam room, hot and cold plunge pool, lounge).
- Banya Spa House Half-Day Journey (up to 4 hours) — Banya venik treatment, full-body exfoliation under a Vichy shower, 60-minute body massage, and a wellness meal.
- Banya Spa House Full-Day Journey (up to 6 hours) — Banya venik treatment, full-body exfoliation, 90-minute body massage, 60-minute facial, and a wellness meal.
For anyone who has done a proper banya in Moscow, St. Petersburg, or one of the New York Russian bathhouses, this is a genuinely faithful version — not a hotel-spa imitation. The therapists are trained in the technique by Aman’s internal wellness team. For anyone who hasn’t, it’s worth booking the 2-hour experience as a first try before committing to the longer journeys.
The massage: an hour at the Aman Spa
The treatment room I was given for an hour-long body massage is the one below.
The bed is wide — closer in scale to a full single bed than a typical massage table — and softer than you’d expect. The walls are finished in a hand-troweled raw plaster with abstract cloud-shaped reliefs (a Denniston signature). The lighting is warm and low, the woven blue-gray curtains diffuse what’s left of the afternoon sun, and the floor is wide-plank oak.
Before the massage started, the therapist did something I haven’t seen at other Bangkok hotel spas: she lit a small bundle of dried Thai herbs, held them at the corners of the bed, and let the smoke fill the room for a minute before clearing it through the ceiling extractor.
The aroma — woody, citrus-edged, faintly smoky — stayed in the room for the full hour. It’s a small ritual but it changes how the treatment lands: calmer, more focused, more deliberate. The massage itself was excellent: medium pressure, a good read of where I was actually tight, and the kind of pacing that doesn’t leave you watching the clock.
And right next door: KHAAN
A two-minute walk from the hotel entrance, on the same Soi Somkid, is one of the best new Thai fine-dining restaurants in Bangkok. KHAAN opened in 2023 and has been on the Michelin Guide since 2024. Chef Sujira “Aom” Pongmorn — the inaugural Michelin Young Chef of the Year for Thailand in 2021 — runs an 11-course tasting menu that pulls ingredients from across Thailand’s four regions and re-presents Thai street food techniques in a fine-dining frame.
KHAAN means both “tiger” (Chef Aom’s birth year) and “to proclaim” in Thai. The restaurant occupies a small two-story house with deep red walls and fewer than 20 covers — it’s an intimate space and reservations are essential.
The menu changes seasonally and leans into less-common regional proteins and ingredients you wouldn’t see on most Bangkok menus. On our visit, one of the standout courses was crocodile tongue — a delicate, almost translucent white meat with a soft, slightly springy texture, served as one of the tasting menu’s protein highlights.
It’s the kind of ingredient Chef Aom uses to make a point: Thailand has a deep tradition of nose-to-tail cooking with farmed crocodile (sustainably raised in the central plains), and the tongue, in particular, is a regional delicacy you almost never see plated at fine-dining level. Beyond that, the menu pulls in Khao Yai duck with five-spice, rice paddy crab from the central plains, wild herbs and traditional ferments from Isaan and the south.
KHAAN Bangkok — 14/3 Soi Somkid, Khwaeng Lumphini, Pathum Wan, Bangkok 10330. Open Tuesday-Sunday 5pm-midnight. Reservations: +66 92 441 6547 or khaanbkk.com. Tasting menu THB 3,850++.
