MUU Bangkok — a design-boutique sanctuary in the heart of Thonglor with Bangkok's most talked-about rooftop pool
Deep in Sukhumvit Soi 55 at the northern stretch of Thonglor, MUU Bangkok is the kind of hotel that design-lovers have been telling friends about since it opened in 2016 and quietly upgraded in 2022. A five-star member of Small Luxury Hotels of the World, it offers 148 all-suite rooms inspired by the 1920s era, a double infinity rooftop pool with a jacuzzi, the acclaimed OTTO Italian restaurant opening directly onto the pool terrace, and a hidden speakeasy bar called 008 that many guests discover only on their last day. The hotel is not a short walk to BTS Thong Lo — it's around 1 km — but a complimentary tuk-tuk shuttle runs throughout the day. Rooms start from approx. THB 3,500/night, with a score of 9.2 from 356 reviews on Trip.com.
Walk through the lobby and MUU Bangkok makes an immediate impression — the 1920s inspiration is specific and committed, not a vague nod to another era. Warm timber floors, considered textiles, brass fittings and leather accents create a boutique atmosphere that feels genuinely curated rather than designed by committee. Guest reviews consistently note that the scale of the property — 148 suites across what feels like an intimate building — makes it personal in a way that larger five-star hotels rarely manage.
Every room is a suite, starting at the 61-sqm Junior Suite and rising to the 180-sqm Thong Lo Suite with its own private terrace. The size alone tends to surprise guests — reviewers regularly describe the Junior Suite as bigger than their own apartment. Bedding quality is praised across platforms, blackout curtains are properly effective, and bathrooms come with both a rain-shower and a freestanding bath. The one recurring note in honest reviews is that walls between rooms are thinner than expected at this price point, meaning corridor and neighbour noise can carry.
"The rooftop pool with jacuzzi and pool bar is absolutely first class. The staff really earn the Small Luxury Hotels badge — nothing is too much to ask, from check-in right through to room service."
The centrepiece is the double infinity rooftop pool: a main pool flowing into a jacuzzi, both overlooking the Thonglor neighbourhood, with a pool bar ready to deliver cocktails without you needing to move. It is one of the more handsome rooftop setups in this part of Bangkok and features in nearly every positive review. OTTO Italian Restaurant opens directly onto the pool terrace, serving classic and contemporary Italian with a well-chosen wine list; the happy hour snack menu is singled out repeatedly as excellent value.
The 008 speakeasy bar is tucked inside the hotel in a deliberate nod to 1920s prohibition-era drinking dens — low lighting, plush seating, cocktails that take their time. The trouble, noted by more than a handful of reviewers, is that the hotel does not proactively point guests towards it: several people discovered it on their final evening, or only after asking at the front desk. If you book, ask at check-in. The MUU Social Club handles breakfast (a buffet praised for variety alongside made-to-order signature dishes) and lighter daytime meals.
On location: MUU Bangkok sits at 88/333 Sukhumvit Soi 55, north Thonglor, roughly 1 km from BTS Thong Lo station. The hotel addresses this with a complimentary tuk-tuk shuttle service running to the BTS and nearby shopping. It works, but it does add a step that guests accustomed to walking straight to the train should factor in. The surrounding area is quintessential Thonglor — independent restaurants, cafés, bars and community malls within easy reach by the shuttle or a short Grab ride.
To be straightforward about the downsides: beyond the thin walls already mentioned, some reviewers flag inconsistent shower temperatures in certain rooms, and occasionally a slight musty smell that suggests some units would benefit from more ventilation. Lighting inside the bathrooms is noted as insufficient in a small number of reviews. None of these is a pattern across the majority of stays — but they are worth knowing about when choosing a room type and floor.
Tips drawn from reading many reviews: mention any special occasion at booking — MUU's team has a well-documented habit of arranging thoughtful surprises (decorated cakes, flowers, handwritten cards) that guests describe as genuinely unexpected. And ask about 008 at check-in, not halfway through your stay. The hotel's combination of all-suite rooms, the rooftop pool and the SLH service standard makes it a strong choice for design-conscious couples and anyone who wants a boutique experience that earns its five-star label.

- 💡If you need to walk to BTS Thong Lo — the hotel is about 1 km away. The complimentary tuk-tuk shuttle runs regularly but does require waiting. If proximity to the station matters more than the boutique atmosphere, consider a hotel closer to the BTS entrance.
- 💡If you are a light sleeper — several reviews mention thin walls and audible noise from neighbouring rooms or the corridor. Ask for an upper-floor room well away from the lift bank when booking to reduce the risk.
- 💡If you want to try the 008 speakeasy bar — ask about it at check-in. The hotel does not advertise it proactively and multiple guests report discovering it only on their last evening, which would be a shame.
