The Residence on Thonglor by UHG — full kitchen and rooftop onsen in the heart of Bangkok's Thong Lo
If you want a place in Thong Lo that feels like actually living there — not just sleeping — The Residence on Thonglor by UHG is what many mid-stay travellers are looking for. The 78 units run from 35 to 58 sqm and every one comes with a working kitchen: full-size fridge, two-burner hob, microwave, washing machine and a full set of cookware. On the roof there's an infinity pool with a panoramic Bangkok skyline view and a men-only Japanese onsen — rare for this neighbourhood. Located at Sukhumvit Soi 55 with a free shuttle to BTS Thong Lo. Rates from approx. THB 2,800/night, with a score of 8.6 from 266 reviews on Trip.com.
The Residence on Thonglor by UHG doesn't compete with boutique design hotels — it occupies a different category entirely: a serviced apartment where you can genuinely live, whether you're in for two nights or two months. The 78 units are sized between 35 and 58 sqm, and what sets them apart is the kitchen. Not a kettle and a microwave shoehorned into a corner, but a proper setup: a full-size refrigerator, a two-burner electric hob, microwave, washing machine, toaster and a complete set of pots, pans and crockery. Reviewers single this out consistently as the thing that surprises them most for the price.
The rooftop is where the property makes its other statement. An infinity pool open to a wide Bangkok skyline — reviewed most warmly at night, when the city lights below are at their most dramatic — sits alongside a men-only Japanese onsen and sauna: a combination that is genuinely unusual among Bangkok's Thong Lo hotels. One recurring review note is that the onsen water temperature can run uncomfortably hot (above 45°C), so it's worth flagging to reception on arrival rather than discovering it mid-soak. The fitness centre, a virtual 18-hole golf simulator and Lek Massage & Spa round out the in-house facilities.
"The room was spacious and spotless, the kitchen had everything — washing machine, full fridge, proper hob. The rooftop pool at night was stunning. Staff were kind and always quick to help."
The location question needs a straight answer: the property sits about 1.8 km deep into Sukhumvit Soi 55, which is a 25-to-30-minute walk from BTS Thong Lo. The hotel addresses this with a free tuk-tuk and shuttle service to the BTS station — but it runs only until 9pm, which becomes a real constraint if your evenings tend to run past that. After 9pm, Grab is your friend. What saves it is the neighbourhood: Thong Lo's best restaurants, cafés and bars are immediately around the property, so on most evenings you may not need the BTS at all.
Staff receive consistent praise across platforms — described as warm, attentive and quick to respond. The property scored 8.8 for cleanliness on Trip.com, and most rooms arrive in solid condition. The honest caveats from reviews: sound insulation is thin in some units — guests have reported hearing neighbours' televisions — and water pressure is weak in certain rooms. Neither is universal, but they're worth knowing before you assume a seamless experience. The gym equipment, meanwhile, is functional but overdue for an upgrade by multiple accounts.
Put it together and the picture becomes clear. For couples wanting a real kitchen and a rooftop onsen in Thong Lo, long-stay travellers who actually want to cook, or families who need space and a washing machine, The Residence on Thonglor delivers something hotels at the same price point in this neighbourhood rarely offer. Rates run from around THB 2,800/night and climb with room size and season. It scores 8.6 on Trip.com (266 reviews), 8.3 on Agoda (6,559 reviews), and holds a TripAdvisor Travelers' Choice 2026 rating of 4.8/5 — ranked #7 among specialty lodging in Bangkok — which for a property of this type says something.
