Quattro by Sansiri Thonglor: Premium Boutique Condo Full Review

Quattro by Sansiri sits quietly on Sukhumvit Soi 55, tucked just deep enough into Thonglor to escape the main road chaos while keeping you minutes from everything. This low rise boutique condo has been a favorite among well heeled expats and Bangkok professionals since it launched, and for good reason. With only 151 units across eight floors, it delivers a sense of exclusivity that the massive high rises on Sukhumvit simply cannot match. If you have been eyeing Thonglor rentals and want something that feels more like a private residence than a condo tower, Quattro deserves a serious look.

Location and Getting Around from Quattro Thonglor

Quattro sits on Sukhumvit Soi 55, roughly 300 meters from the main Sukhumvit Road intersection. BTS Thong Lo station is about a seven minute walk, which is manageable most of the year but can feel long during April heat. Most residents here just grab a motorbike taxi from the soi mouth for 20 to 30 baht.

The real magic of this location is what surrounds you on foot. J Avenue is practically next door for quick coffee runs and casual dining. Eight Thonglor, the lifestyle mall with its mix of restaurants and boutiques, is a short walk south. If you need a proper grocery run, Tops Market at The Commons Thonglor or the bigger Villa Market on Soi 33 are both easy to reach.

For families, Bangkok Prep International School on Soi 53 is nearby, and several other international schools run shuttle routes through Thonglor. One Japanese expat family I know chose Quattro specifically because the school bus for their kids stops right on Soi 55, and they can walk to their favorite izakaya on Soi Thonglor 13 for Friday dinners.

Unit Types, Layouts, and What to Expect Inside

Quattro offers one bedroom, two bedroom, and three bedroom units ranging from about 56 to 245 square meters. The one bedrooms start around 56 sqm, which is generous compared to the 30 sqm shoeboxes you find in newer Thonglor launches. Two bedrooms typically run 90 to 130 sqm, and the three bedrooms push well past 200 sqm with proper living and dining separation.

The interiors lean toward a clean, modern aesthetic with warm wood tones. Ceilings feel higher than average for Bangkok condos, and most units get solid natural light thanks to the low rise design and spacing between buildings. Kitchens come with full size appliances, including an oven, which is a detail that sets Quattro apart from many condos where the kitchen is basically decorative.

A friend of mine rented a two bedroom corner unit on the sixth floor for two years. She loved the bathtub, the separate kitchen, and the fact that her balcony actually had space for a small table and two chairs. Her one complaint was that some of the fixtures felt dated compared to newer builds, but Sansiri has maintained the common areas well.

Facilities and Community Feel

Do not expect the Instagram worthy infinity pools and coworking spaces you see in new launches. Quattro keeps things refined and practical. There is a swimming pool surrounded by greenery, a well equipped fitness center, a sauna, and 24 hour security with key card access throughout.

The lobby feels more like a boutique hotel than a condo reception. It is quiet, well maintained, and the management team is responsive. Parking is adequate for a building this size, with most units getting at least one dedicated space.

What really defines the living experience here is the community. With only 151 units, you start recognizing your neighbors quickly. The building skews toward long term residents rather than short stay tourists, which keeps noise levels low and common areas pleasant. A British couple I know who moved from a larger condo on Sukhumvit Soi 24 said Quattro felt like "moving from an airport hotel to an actual home."

Rental Prices and Value for Money

Expect to pay around 35,000 to 50,000 THB per month for a one bedroom at Quattro. Two bedrooms typically land between 55,000 and 85,000 THB, depending on floor, furnishing, and whether it has been recently renovated. Three bedrooms can push past 100,000 THB, especially for the larger corner units with premium views.

Is that expensive? For Thonglor, it is actually mid range. Compare it to newer options like TELA Thonglor or The Monument Thong Lo, where two bedrooms easily start at 90,000 THB and climb fast. Quattro gives you the Sansiri build quality, the prime Thonglor address, and significantly more space per baht than most competitors built after 2018.

The trade off is age. Quattro was completed in 2011, so it does not have the latest smart home features or the ultra modern lobby designs. But for renters who prioritize space, quietness, and a genuine neighborhood feel over flashy amenities, it punches well above its price point.

Who Should Rent at Quattro Thonglor

This condo works best for professionals and small families who want a residential feel in one of Bangkok's most vibrant neighborhoods. If you work in the Asoke or Phrom Phong area, the commute via BTS is two to three stops. If you work remotely, the spacious units and quiet environment make it easy to set up a proper home office.

It is less ideal if you want brand new finishes, a rooftop bar vibe, or a condo that doubles as a social scene. Quattro is for people who want to come home to calm after a long day in Bangkok.
