Don't want to offend anyone but cleanliness is basic house rule to me. If you are not sure if you can reach my standard, for example, long travelers who will take long bus and long walk before coming and don't have habit to wash before sleeping, don't come to my home. By the way, I like couchsurfering's concept and like sharing with people except you don't appreciate host's kindness and treat CS like motel, please don't request.
