I'm not the type of person who complains about cheap places. I know what I'm paying for, but, in the case of Green Guest House, I need to tell you that I had to just cut my loses and go somewhere else.
Normally, I would look past the soiled sheet and the hairs and bodily fluids and just sleep with my clothes on, but it would've been too warm in the rooms for this. There was also this pervasive sewage smell and, yeah, I know at this price I can't expect the Ritz, but the smell was so strong, especially without much ventilation, it was hard not to gag on it.
For another hundred baht you can find a much more comfortable place. Unless your just looking for a bed to pass out in, I would strongly consider avoiding this place.
