Oakwood Suites Bangkok — 5-Star Serviced Apartments with an Infinity Pool in the Heart of EM District
Sukhumvit Soi 24 sits in one of Bangkok's most liveable pockets — Japanese restaurants and convenience stores on the doorstep, the Emporium–EmQuartier–EmSphere shopping complex a few minutes' stroll away, and BTS Phrom Phong just three minutes on foot. Oakwood Suites Bangkok capitalises on all of this with 228 fully-equipped serviced apartments in a 35-storey tower at number 20 in the soi. Every unit comes with a full kitchen, washer-dryer, and a minimum 40 sqm of living space. The headline feature guests mention most is the rooftop salt-water infinity pool with open city views — and a gym that regulars say outperforms many conventional five-stars in Bangkok. From approximately ฿3,500/night, with a score of 9.1 from 676 reviews on Trip.com.
Oakwood is an established Asia-Pacific serviced-apartment brand, and its Bangkok Suites property at 20 Sukhumvit Soi 24 is aimed squarely at both short-break visitors and long-haul corporate relocations. The 35-floor tower holds 228 fully furnished units — not hotel rooms that happen to have a kitchenette, but genuine apartments with full-sized refrigerators, electric hobs, washer-dryers, and a Nespresso machine in every unit. The hotel received GSTC sustainability certification in 2025, a sign that the management team takes operations seriously.
Location is the single most consistent theme across all guest reviews. BTS Phrom Phong is a three-minute walk from the lobby, giving direct access to Asok, Siam, and every major transport hub without stepping into a taxi. Emporium Shopping Complex is at the end of the soi; EmQuartier sits just across Sukhumvit Road and EmSphere a few minutes further — together making up the EM District, arguably Bangkok's most walkable stretch of retail and dining. The surrounding streets are dense with Japanese restaurants, izakayas, Japanese grocery stores, and quality Thai massage parlours — a legacy of the neighbourhood's longstanding Japanese expat community.
"The gym is far better equipped than many five-star hotels I have stayed at — clean, well-maintained, and never crowded. That alone makes a business trip so much more manageable."
Room sizes start at a 40 sqm Premier Apartment — compact by Oakwood standards but still larger than a standard room in most Bangkok hotels — and scale up through Studio Deluxe (45 sqm), One-Bedroom Superior (55 sqm), One-Bedroom Deluxe (60 sqm), One-Bedroom Executive (60 sqm), and Two-Bedroom apartments to a Two-Bedroom Executive at 105 sqm that sleeps four adults comfortably. All units include 45-inch Smart TVs, blackout curtains, powerful air conditioning, and strong water pressure in the bathrooms. The kitchen genuinely works: the hob, fridge, and dishware are sized for actual cooking, not just reheating.
The rooftop salt-water infinity pool is the visual centrepiece — an outdoor pool with open Bangkok skyline framing, particularly attractive at sunset. The fitness centre on the fourth floor draws specific praise in dozens of reviews for the quality and variety of its equipment; business travellers in particular cite it as a key reason to return. Sauna, a children's play room, a residents' lounge, a library, and a co-working space round out the amenity list, making this a genuinely self-contained option for longer stays. ACORN Cafe handles all-day dining, though reviews are lukewarm — the consensus is to venture into the soi for real meals.
Guest sentiment across 676 Trip.com reviews is strongly positive, with the highest marks reserved for location (9.4), cleanliness (9.2), and service (9.1). Staff are repeatedly described as friendly, professional, and responsive. The few recurring complaints are specific: some units have ageing furniture that is starting to show its years, a handful of TVs are older models pending replacement, and the pool occasionally closes for maintenance without prior notice. For families, it is worth checking pool availability in advance if swimming is central to the plan.
Against other five-star options on Sukhumvit Soi 24 and the surrounding streets, Oakwood Suites Bangkok offers genuine value for anyone who wants apartment-style living in a prime Phrom Phong address. Studio and Premier units run from approximately ฿3,500 per night; a Two-Bedroom Executive for four people comes in around ฿8,500–฿10,000 depending on season. The longer you stay, the more the full kitchen and washer-dryer pay back — three or more nights and the arithmetic tends to work in your favour compared to a conventional hotel at the same price tier.
Summary from Booking & Agoda
- ✓ Outstanding location — 3 to 5 minutes on foot to BTS Phrom Phong and Emporium mall
- ✓ Spacious, spotlessly clean rooms with fully equipped kitchen and washer-dryer
- ✓ Gym equipment is excellent — stands out even against dedicated five-star hotels
- ✓ Friendly, efficient staff who handle requests quickly
- ! Breakfast at ACORN Cafe is underwhelming relative to the price; the surrounding soi is far better for dining
- ! Some units have older furniture and fixtures that would benefit from a refresh
- ! English-language TV channel selection is limited
- ✓ Prime Phrom Phong location — BTS, Emporium, EmQuartier all walkable
- ✓ Large rooms with working kitchen and in-unit washer-dryer, ideal for extended stays
- ✓ Infinity pool with city views; gym consistently praised as best in class
- ✓ Fast, reliable Wi-Fi throughout
- ! Pool occasionally closed for maintenance without advance notice, frustrating for families
- ! Isolated drain issues and dated appliances in a minority of units
- ! Restaurant on-site is average — guests are better off eating in the neighbourhood
- 💡If in-hotel dining is important to you — ACORN Cafe gets middling scores from guests. The soi has far better Thai and Japanese breakfast options at comparable or lower prices; factor in a walk rather than relying on room service.
- 💡If you are only staying one or two nights — the apartment-format premium is most justified over three nights or more, when the kitchen and laundry facilities genuinely save money. Conventional hotels on the same street may offer better short-stay value.
- 💡If pool access is central to your trip — the infinity pool does undergo maintenance closures. It is worth messaging the hotel in advance to check the schedule for your dates.
