I guess this question relates to the answerer.

With hundreds of guest houses around town, Bangkok can be one of the most difficult places in Thailand to decide on a place to stay. Although the area of Khao San Road is popular in other parts of Bangkok are just as good if not better. So do not rush to follow the hordes of Khao San Road - Do your research - there are many other options out there - and choose a guest house that will fit your budget, depending on your style and you can do what you must do it easily.
First up, determine why you stay in Bangkok and what you do. In Bangkok the mantra is location, location, location, and unless you want to spend half your time in traffic, you should consider somewhere close to your area of interest. The construction of the BTS and the subway have to move areas much easier, but large areas remain completely undeveloped - including Khao San Road.
