New to hosting and somehow I feel I may have guested a homeless person. He is working however when he came to the door he had three huge bags and an odor that was hard to describe. Anyone else came across this or have had guests like these that are basically drifters who pay for a room. My question is should I be alerted? He already paid and is pretty good at keeping the room okay however he mounds of dirty clothes on the second day made me think this guy is just using AirBnb as cheap rent.
