Choosing the right hostel can take some internet research and sometimes word of mouth from other travelers helps. Your mood is also a factor. I chose a hostel in Bangkok that appealed to me because of its location away from a busy noisy area. It seemed to have a few things within walking distance to check out, local bus stops, and a short 750m walk to the famous (or should I say infamous?) Khaosan road. The Here Hostel had photos showing a rustic charm and pleasant garden area. Having a pool was also a plus.
