If you have been living in Bangkok for any length of time, you already know that On Nut is where the smart money goes. It is the sweet spot between city access and affordable rent, and The Base Sukhumvit 77 sits right in the middle of that equation. This Sansiri development has been a reliable mid-range option since it opened, and heading into 2026, it remains one of the most popular choices for renters who want a BTS lifestyle without the Thong Lo price tag. Let me break down everything you need to know before signing a lease here.

Location and Getting Around from The Base Sukhumvit 77

The Base Sukhumvit 77 is located on Sukhumvit Soi 77, also known as On Nut Road, roughly a 10 minute walk from BTS On Nut station. That walk is flat and mostly shaded, so it is manageable even in the hot season. Some tenants grab a motorcycle taxi from the BTS exit for 15 to 20 baht, which cuts the trip to about two minutes.

From BTS On Nut, you are three stops from Ekkamai, five stops from Phrom Phong, and about 25 minutes from Siam. That commute is realistic for anyone working in the central business districts around Asoke or Silom. Just budget extra time during morning rush, roughly 7:30 to 9:00 AM, when trains get packed from this end of the line.

For everyday errands, Tesco Lotus On Nut and Big C are both within a short drive. Century The Movie Plaza is right across the street from the BTS station, and the On Nut fresh market on Soi 77/1 is a five minute walk from the condo. One friend of mine who teaches at an international school near Bearing does her entire weekly grocery run at that market for under 800 baht. That is the kind of neighborhood this is.

Unit Types, Sizes, and What You Will Actually Pay

The Base Sukhumvit 77 offers studios and one bedroom units. Studios range from about 26 to 30 square meters, while one bedrooms sit around 34 to 38 square meters. The layouts are efficient, very typical Sansiri design with built-in furniture, a compact kitchen counter, and floor-to-ceiling windows that bring in good natural light.

As of early 2026, expect to pay around 9,000 to 12,000 baht per month for a studio depending on floor, view, and furnishing condition. One bedroom units go for roughly 13,000 to 17,000 baht. These prices make The Base Sukhumvit 77 one of the most competitive options along the Sukhumvit corridor, especially compared to similar Sansiri projects closer to Thong Lo where you would easily pay double.

A couple I know relocated from a 15,000 baht studio in Phra Khanong to a one bedroom here for 14,500 baht. They gained a bedroom wall, a better pool, and a lower electricity bill because the building's common area charges are reasonable. That kind of value upgrade is typical for tenants who are willing to move one or two BTS stops further out.

Facilities and Day to Day Living

The building has two towers, Tower A and Tower B, connected by a shared amenity floor. The rooftop pool is the highlight. It is not huge, but it has a decent view and rarely gets overcrowded on weekday evenings. There is also a basic gym with cardio machines and free weights, a co-working lounge area, and a small garden terrace.

Security uses a key card system for the lobby, elevators, and pool area. There is 24 hour security at the front desk and CCTV throughout the common areas. Parking is available but limited, so if you have a car, confirm a spot before you commit to a lease.

One thing tenants appreciate is the ground floor convenience. There is a 7-Eleven right at the base of the building and a few small food shops nearby. After a late night coming back from Thong Lo, you can grab a meal and be in your unit within minutes. That kind of convenience sounds small, but it adds up when you live it every day.

Who This Condo Works Best For

The Base Sukhumvit 77 attracts a mix of young Thai professionals, entry-level expats, English teachers, and remote workers. It is not a luxury building, and anyone expecting the finishes of a Thong Lo high-rise will be disappointed. But for the price point, the quality is solid and the location delivers.

This condo works especially well for single renters or couples on a combined budget of 30,000 to 50,000 baht per month. At that income level, spending 12,000 to 15,000 baht on rent here leaves plenty for food, transport, and the occasional weekend trip to Koh Samet. A digital nomad I met at a co-working space on Ekkamai moved here specifically because the internet speed in the building tested consistently above 200 Mbps, which was faster than what he got at a pricier place near Nana.

Things to Watch Out For

No condo is perfect, and The Base Sukhumvit 77 has a few things to keep in mind. First, the walk from BTS On Nut can feel long if you are carrying groceries or walking in the rain. A foldable umbrella becomes a permanent bag item. Second, some of the older units have wear on the furniture and fixtures, so always inspect before signing. Ask to see the actual unit, not a showroom or photos from three years ago.

Third, noise can be an issue on lower floors facing Soi 77, which gets busy with traffic during peak hours. If you are a light sleeper, request a unit on a higher floor facing the interior of the project. Finally, the building has a lot of units, so elevators during morning rush can involve a short wait. Not a dealbreaker, but good to know.

Overall, The Base Sukhumvit 77 remains a strong mid-range pick for 2026. It delivers solid value, a convenient On Nut lifestyle, and the reliability of a Sansiri-managed property.
