Real budget accommodation is hard to come by, and where it does exist it's often grotty. At the US$20 to US$40 level you might get a fan or TV, but running water is still unlikely. Move into the US$50 to US$100 range and rooms will be much more comfortable, but no matter what you pay, your hotel will usually be much simpler than similarly priced properties back home.
