With accommodation, you get exactly what you pay for. Generally, Bangkok, Phuket and Ko Phi Phi have the most expensive backpacker accommodation. On the islands, Ko Pha Ngan is probably among the cheapest.
The following applies to Khao San Road.
Under 100B: Gets you a dorm room with a fan or a very grotty single room with a smelly mattress, noisy fan and share bathroom. The sheets, if there are any, will only be changed when you leave. Expect thin walls and dreary drapes and plan on spending as much time as possible elsewhere.
100B-250B: Gets you a typical budget room. The higher end of this range should get you a room including your own bathroom that will be moderately clean. The room will be big enough for a clean bed with sheets, and a couple of bags, plus maybe a chair or two. It may have either a large ceiling fan or a small desktop one.
250B-500B: Gets you a decent fan or basic air-con room, which should be clean and well kept and include a good bathroom. Your bed will have a clean mattress and sheets. Generally larger than the lower price range, these rooms often have a desk and chair. You might even get something tasteful.
500B-1,000B: Gets you a spotless room with reliable air-con, a comfortable bed and a clean, well-equipped bathroom. The room will be spacious and may have a few extras such as a bar fridge and TV with limited cable.
1,000B+: As the price rises from here, expect more extras, such as TV with full cable, DVD player, a mini-bar, balcony, breakfast and so on.
