I strongly recommend to Airbnb to watch out about this person.
First, he has change his name from the name he used on his original reservation (his name was Michael and NOT Gerard) so that it is giving you a reference of what king of person it is and he also change his picture so he is not recognizable now from the original one he used. Please, be careful with this person (in case Airbnb need his picture from the reservation I have it available)
Second, he show up the first night (and every day after) drunk so how could I be friendly to him and how trustable he could be.
Third, he mention no ground rules on my place. Well, he knew he was renting a bedroom and a private bathroom as every single guest has done and, the rules, as I had done with everybody else were than I had the courtesy to allow some extra things to be use (with care) as, for example, the terrace and, also, allow to save a few things on my refrigerator, NO as he did, living dirty cloth and socks, cigarette ashes all over as well as books and other stuff (by the way, I had available for Airbnb, photos of that on most of the days he stayed here just in case Airbnb need it and I captured because I knew he was trouble from the beginning )
Beside that, he also used half of my refrigerator and while I was not at home he used my washing machine and stove. And that is UNACCEPTABLE.
Anybody could read the opinions of every single guest before him, to know how clear the rules were and how welcome they felt.
I could keep talking about this person on other aspect of his manners but it is not worth my time because Airbnb did already informed about problem I was having with this person several days before he left. I had talk to a Airbnb representative and informed him about all this details and we agree on how to handle the situation.
So, stop laying Mr. Michael or Gerard or whatever your name is.
And yes, use a hotel next time and do not bother at other people's home
