The Room Sukhumvit 21: Asok Boutique Condo Full Review 2026

If you have been hunting for a condo near Asok that feels more like a private residence than a cookie-cutter high rise, The Room Sukhumvit 21 has probably popped up on your radar. Sitting on Soi Sukhumvit 21, just a short walk from both BTS Asoke and MRT Sukhumvit, this low-rise boutique project by Land and Houses has quietly built a loyal following among expats and Thai professionals who want Asok convenience without the chaos of a 40-story tower. I have visited this building multiple times and know several tenants who have lived here. This is the full, honest review for anyone considering it in 2026.

Location and Getting Around from Sukhumvit 21

The Room Sukhumvit 21 sits about 450 meters into Soi 21, also known as Asoke Montri Road, one of the busiest and most connected sois in all of Bangkok. You are roughly a 6 to 7 minute walk to BTS Asoke station and about the same distance to MRT Sukhumvit station. That gives you access to both rail lines from a single location, which is something a lot of condos further down Sukhumvit simply cannot offer.

Imagine you work at Exchange Tower or one of the offices along Ratchadaphisek. Your commute is either a 10 minute walk or one MRT stop. Need to get to Siam? Four stops on the BTS. Heading to Chatuchak on a weekend? The MRT runs straight there. This kind of dual rail access is a genuine lifestyle upgrade, especially during rush hour when Bangkok traffic turns even a 3 kilometer taxi ride into a 40 minute ordeal.

Day to day, you have Terminal 21 mall right at the intersection for groceries, food courts, and shopping. Robinsons Department Store is across the road. Villa Market on Soi 33 is a short motorbike taxi hop away. For healthcare, Bumrungrad International Hospital is literally on the same soi, less than 5 minutes by car. That proximity to Bumrungrad alone makes this building attractive to medical tourists and families who want world-class healthcare within walking distance.

Building Design and Unit Layout

The Room Sukhumvit 21 is an 8-story building completed in 2012 by Land and Houses, one of Thailand's largest listed developers. With only around 270 units total, it has a boutique feel that taller Asok towers like The Edge Sukhumvit 23 or Supalai Premier Asoke simply cannot replicate. Hallways are quiet. Elevators are rarely crowded. You actually recognize your neighbors.

Units come in studio, one bedroom, and two bedroom configurations. Studios start around 24 square meters, one bedrooms range from 33 to 45 square meters, and two bedrooms go up to about 60 square meters. The interiors lean toward a warm, modern Thai aesthetic with wood tone finishes, built in wardrobes, and kitchenettes that are functional enough for light cooking. Full floor to ceiling windows let in good natural light, particularly in units facing south or east.

Here is a practical example. A couple relocating from Chiang Mai to Bangkok for work recently rented a 40 square meter one bedroom here. They chose it specifically because the layout separates the sleeping area from the living space with a proper wall, not just a curtain or partition. That full separation is surprisingly rare in Bangkok condos at this price range, and it makes a real difference when one person is on a video call while the other is watching TV.

Facilities and Daily Living Experience

Do not expect the resort style amenity deck you would find at a place like Ashton Asoke or The Esse Asoke. The Room Sukhumvit 21 keeps things practical. There is a rooftop swimming pool, a basic fitness room, a lobby lounge area, keycard access, and CCTV security. The pool is small but rarely crowded, which is honestly a better experience than fighting for lane space at a bigger building's infinity pool.

The gym covers the basics with treadmills, an elliptical, free weights, and a cable machine. If you are serious about fitness, you will probably want a membership at Fitness First Terminal 21 or one of the CrossFit boxes nearby. But for a morning run on the treadmill or a quick workout after work, it does the job.

Building management is generally responsive. Common areas are kept clean. One thing tenants consistently mention is the quiet atmosphere. Because the building is only 8 stories with a manageable number of units, you avoid the party crowd that sometimes takes over larger Asok condos. If you are a working professional who values sleep and quiet evenings, this matters more than a fancy sky lounge.

Rental Prices and What You Should Expect to Pay

As of early 2026, average rent for a one bedroom unit at The Room Sukhumvit 21 ranges from 18,000 to 25,000 THB per month, depending on floor level, furnishing quality, and whether the landlord has recently renovated. Studios can go for as low as 13,000 to 16,000 THB. Two bedrooms typically ask between 28,000 and 38,000 THB per month.

To put this in context, the average rent for a one bedroom condo in the Asok to Phrom Phong corridor sits around 25,000 to 35,000 THB per month according to recent market data from DDproperty. That means The Room Sukhumvit 21 comes in at the lower to mid range for the area, making it a strong value pick for anyone who wants Asok access without paying Asok premium prices.

A friend of mine, a single expat working in digital marketing, rents a one bedroom here for 20,000 THB per month. His previous place was a studio at a newer building near BTS Thong Lo for the same price but half the space. He says the trade off is obvious. More space, better location for transit, and a quieter building, all for the same monthly cost.

How It Compares to Nearby Condos

Choosing a condo in Asok means you have plenty of options. Here is how The Room Sukhumvit 21 stacks up against some of the most commonly compared buildings in the immediate area.

Condo Name	Distance to BTS Asoke	Year Completed	1-Bed Rent (THB/month)	Total Units	Building Height
The Room Sukhumvit 21	6-7 min walk	2012	18,000-25,000	~270	8 floors
Edge Sukhumvit 23	5 min walk	2015	22,000-30,000	~250	8 floors
Rende Sukhumvit 23	4 min walk	2015	20,000-28,000	~300	8 floors
Supalai Premier Asoke	3 min walk	2014	18,000-26,000	~650	38 floors
Ashton Asoke	1 min walk	2018	30,000-45,000	~580	50 floors

The comparison tells an interesting story. If you want the absolute closest walk to the BTS and do not mind paying a premium, Ashton Asoke is hard to beat. But if you want a quieter, lower density building at a significantly lower price point while still being in the Asok zone, The Room Sukhumvit 21 and the nearby Edge and Rende projects on Soi 23 compete closely. The Room edges ahead on value when landlords price competitively, and its location on Soi 21 gives it the Bumrungrad Hospital proximity advantage.

Who This Condo Is Best For (and Who Should Look Elsewhere)

The Room Sukhumvit 21 is ideal for working professionals, couples, and small families who want a central location without the noise and density of a mega tower. It is a great pick for anyone who commutes via BTS or MRT, shops at Terminal 21, or works in the Asok to Ratchadaphisek corridor. Medical professionals or patients connected to Bumrungrad will find the location incredibly convenient.

Consider a real scenario. A Japanese expat family with one child recently moved here because the father works at a trading company on Ratchadaphisek, the mother wanted easy access to BTS for trips to Siam, and they both wanted Bumrungrad nearby for their child's checkups. A two bedroom unit at 32,000 THB per month checked every box.

However, if you are looking for a brand new building with luxury amenities like a co-working space, sky lounge, or resort pool, this is not your building. It is 14 years old now, and while it has been maintained well, it does not have the wow factor of newer developments. If you crave nightlife and want to stumble home from Soi 11 bars, you might prefer something closer to BTS Nana. And if you need a large unit above 70 square meters, you will need to look at older buildings or move further from the BTS.

The Room Sukhumvit 21 is one of those condos that does not try to impress you with flashy marketing or Instagram-worthy infinity pools. It earns its reputation through practicality, location, and value. For renters in 2026 who want solid Asok living at a fair price, it deserves serious consideration.
