The XXXIX Sukhumvit 39: Compact Phrom Phong Condo Reviewed

If you have been condo hunting along Sukhumvit, chances are The XXXIX Sukhumvit 39 has popped up on your radar. Sitting on one of the most walkable sois in Phrom Phong, this low-rise development has built a quiet but loyal following among renters who want a boutique feel without sacrificing location. But is it actually worth the rent, or are you better off looking at one of the dozens of other options in the area? I have walked through multiple units here, talked to tenants, and compared it against the competition. Here is what you need to know before signing anything.

Location and Getting Around from Sukhumvit 39

The XXXIX Sukhumvit 39 sits roughly halfway down Soi 39, one of the longest and busiest sois branching off Sukhumvit Road. From the lobby, you are looking at about a 10 to 12 minute walk to BTS Phrom Phong station, which puts you on the Sukhumvit Line with direct access to Asok, Siam, and beyond. It is not the closest condo to the station, and during rainy season that walk can feel long. But the tradeoff is a quieter stretch of soi compared to the chaos near the main road.

What makes Soi 39 special is the density of everyday amenities. You have got Villa Market about five minutes on foot, Fuji Super nearby, and a string of Japanese restaurants, coffee shops, and laundry services. Samitivej Hospital is just down the road if you need medical care. Families with kids will notice that The Emporium and EmQuartier malls are both within a short taxi or motorbike ride.

Here is a real scenario. Say you work at one of the offices near Asok or Nana. Your morning commute is a short motorbike taxi to BTS Phrom Phong, then two stops on the train. Total door to desk time is around 20 to 25 minutes on a good day. That is competitive for this part of Bangkok.

Building Overview and Unit Layouts

The XXXIX Sukhumvit 39 is an eight-story, low-rise condominium completed around 2011 by Sansiri, one of Thailand's biggest developers. The project has roughly 250 units, and the overall design leans modern with clean lines, neutral tones, and a lobby that feels more hotel than apartment block. Sansiri's build quality at this price tier is generally solid, though not luxury grade. Think well-above-average finishes with reliable plumbing and electrical systems.

Unit sizes are where things get interesting, and sometimes frustrating. Most one-bedroom units here come in at around 30 to 40 square meters. Two-bedroom units range from roughly 55 to 75 square meters. By Bangkok standards these are compact, especially at the lower end. If you are coming from a Western country and expect a spacious living area, the smaller one-beds might feel tight once you add a desk and a wardrobe.

Picture this. A couple relocating from Singapore finds a 39 square meter one-bed unit here for 28,000 THB per month. The bedroom fits a queen bed and a small nightstand. The living area works for a two-seater sofa and a TV. There is no room for a dining table, so meals happen at the kitchen counter. It is functional, but you need to be realistic about the space.

According to data from DDproperty, the average asking rent for a one-bedroom condo in the Phrom Phong area ranges from 22,000 to 38,000 THB per month depending on building age, floor level, and furnishing quality. The XXXIX tends to land right in the middle of that range.

Facilities and Day to Day Living

For a low-rise building, The XXXIX punches slightly above its weight on amenities. You get a rooftop swimming pool, a decent gym with cardio and weight equipment, a garden area, and 24-hour security with key card access. There is also parking for residents who drive, though spots can fill up quickly during peak hours.

The pool is one of the building's highlights. It is on the rooftop with a partial city view, and because the building is not massive, it rarely feels overcrowded. Compare that to some of the mega-projects along Sukhumvit where you are sharing pool space with 500 other units. The gym is fine for basic workouts but serious lifters will probably want a Fitness First or Jetts membership nearby.

One thing tenants consistently mention is the management team. The juristic office is responsive to maintenance requests, and common areas are kept clean. That might sound like a small thing, but anyone who has lived in a poorly managed Bangkok condo knows how quickly things can deteriorate. Broken elevators, dirty hallways, unresponsive staff. The XXXIX avoids most of those headaches.

A practical example. A remote worker living alone uses the lobby and garden area as a change of scenery from the apartment. The Wi-Fi does not extend to common areas, so she hotspots from her phone, but the environment is quiet enough to take calls. Not a co-working space, but a nice break from staring at the same four walls.

Rental Prices and What You Actually Pay

Let us talk money. As of 2024 and into 2025, rental prices at The XXXIX Sukhumvit 39 generally fall into these ranges. One-bedroom units go for approximately 25,000 to 35,000 THB per month. Two-bedroom units typically ask between 40,000 and 55,000 THB per month. Larger or renovated units on higher floors can push past 60,000 THB.

These figures are in line with what FazWaz lists for comparable Sansiri projects in the Phrom Phong to Thong Lo corridor. You are not getting a bargain, but you are not overpaying either, assuming the unit is well maintained and fully furnished.

On top of rent, expect the usual Bangkok condo costs. Electricity runs 7 to 8 baht per unit from the building's meter, which means your monthly electricity bill for a one-bed with moderate air conditioning use lands around 2,500 to 4,500 THB. Water is minimal, usually under 500 THB. Internet from a provider like AIS or True runs 600 to 900 THB for fiber.

Security deposits are standard at two months' rent plus one month advance. So for a 30,000 THB unit, you are putting down 90,000 THB upfront before you move a single box in. That is worth budgeting for, especially if you are new to Bangkok and also covering visa expenses and furniture top-ups.

How The XXXIX Compares to Nearby Condos

Phrom Phong has no shortage of rental condos. Here is how The XXXIX stacks up against some of the most common alternatives renters consider in this neighborhood.

Building	Distance to BTS Phrom Phong	1-Bed Size (sqm)	1-Bed Rent (THB/month)	Year Completed	Building Style
The XXXIX Sukhumvit 39	10 to 12 min walk	30 to 40	25,000 to 35,000	2011	Low-rise, boutique
Siri at Sukhumvit 38	5 to 7 min walk	40 to 60	28,000 to 42,000	2009	Low-rise, family-friendly
Noble Solo Thonglor	15 min walk (closer to Thong Lo BTS)	40 to 50	25,000 to 38,000	2008	Low-rise, modern
Park 24 (Park Origin)	3 to 5 min walk	28 to 35	22,000 to 32,000	2018	High-rise, compact
Aequa Sukhumvit 49	12 to 15 min walk	30 to 45	20,000 to 30,000	2013	Low-rise, quiet

A few things jump out. Park 24 gives you the closest BTS access and a newer building, but the units are tiny and the high-rise environment feels very different from The XXXIX's boutique vibe. Siri at Sukhumvit 38 offers more space per unit but sits on the even-numbered side of Sukhumvit, which some renters find less convenient for the Japanese-centric amenities concentrated on Soi 39. Aequa on Soi 49 is the budget pick, though the extra distance from BTS starts to matter if you commute daily by train.

The sweet spot for The XXXIX is the renter who values a calm, well-managed building on a convenient soi and does not mind the slightly smaller floor plans. If maximum space is your priority, look at Siri at Sukhumvit 38. If BTS proximity is everything, Park 24 wins that contest easily.

Who Should Rent Here and Who Should Not

The XXXIX Sukhumvit 39 works best for singles and couples, particularly professionals or expats on mid-range budgets who want to live in the Phrom Phong area without paying Sukhumvit Road frontage prices. It also suits people who prefer low-rise buildings with fewer neighbors and a quieter atmosphere.

It is less ideal for families with children who need extra bedrooms and play space. The two-bedroom units can work for a small family, but you will feel the squeeze. Families might be happier on Soi 49 or Soi 63 where larger units and international schools are closer. If you have kids in school at Bangkok Prep or NIST, the commute from Soi 39 is manageable but not the shortest option.

Consider a solo expat working in digital marketing from home three days a week and heading to an office near Asok on the other two. A one-bed unit at 30,000 THB puts her in a solid building, steps from good food and grocery stores, with a pool for after-work swims. That is the profile where The XXXIX really shines.

The XXXIX Sukhumvit 39 is not the flashiest condo in Phrom Phong, and it is not trying to be. It is a well-built, well-located, well-managed mid-range option on one of Bangkok's best sois. If that checks your boxes, it deserves a spot on your shortlist.
