This guest was not only difficult but unsafe to deal with. He did not respect the rules of the house which indicated that in order to bring a guest he needed permission from the host. He not only never asked for permission but brought a woman to my house late at night and tried to impose her presence to my mother who is 66. He exchanged words with my mother and did not aknowledge the mistake. He lied saying that he did have permission from me who was not in the house at the time. In addition, he received a refund from me by mistake and seeked a double refund from Airbnb. My experience with this guest was two days of terror with my mother being agitated by his behavior which was at some point erradic ( left late at night, came back 4 or 5 in the morning). I will advise you for the sake of your peace of mind to please not to rent to him. See his previous negative reference which I did not consider when I rented the room. My big mistake!
