coming to the north of ghana, one should not have high expectations of comfort, but one should expect to pay little as a result.
My room with aircon and shared bath was 25 cedis (about $18) per night. Here are the highlights: cockroaches, windows that don't clos (hence mosquitos in a malaria area), two mice, five days to replace bathroom light, five days to empty trash bin, no hot water, meagre brreakfast, and most staff that don't speak english. I would pay 5 to 7 cedis for all this, because my room did at least have aircon. On every other front the hotel is grossly over priced.
