What are the best and or cheapest Neighbourhoods to live in/close to Bangkok?
Bangkok is huge and unorganized urban planning. It have poor traffic all the time. Better to live in neighborhoods where MRT, BTS or airport links lines passed.
Mentioned in this answer:
I stayed in Bang Rak and Khao San Road. Bang Rak was more of a business traveler area but lots of swanky hotels. Khao San Road had more back pack travelers like me, but still a nice area and pretty cheap.
