I'm having a search now. I seem to remember to cheap one called Happy or something like that but can't find it anywhere near where I remember it on the maps. Maybe it's not even listed. But if you get away from Khaosan road a bit onto Phra Aphit road, it gets cheaper for single rooms. On the maps, the one I stayed at twice was at about 82 Phra Aphit Road but on the corner there. Not Khao San Art hotel... anyways, goodluck!
