I’ve been to Bangkok several times and this area (Pinklao) is my new favorite. Between the Maruay Food Hall and the Indy Night Market, there’s a lot of solid food options when on a budget.
Staying in the studio room as a couple was quite comfortable. There’s on-site laundry machines and as others may have mentioned, the owners are quite hospitable. The room was clean and tidy, the A/C unit was more than adequate and the water pressure in the bathroom was powerful. There are several buses within a 5 minute walk, one of which (511) takes you to Khao San Road for only 11 baht.
All-in-all, I recommend this place if you want to take a break from the touristy track.
