We stayed 3 nights at Phi Phi Inn, we saw the scary reviews but we didn't have any trouble with any sort of bugs, the room was clean and was cleaned regularly.
Air con worked well and was quiet, staff were helpful when asked e.g. how to use the safe.
Location was very close to the pier and main shopping areas and beaches.
Obviously it's not a 5 star resort, it was basic but did the job and was affordable!
