It'll be thumbs down for sure. I've finally gotten Airbnb involved. He woke me at 5 AM with shouting to himself in his room. We have a written and spoken rule of quiet time between 10 PM and 8 AM. Then he started to walk in on me in the bathroom. He knows to see if the light is on, as it shows under the door, and not to attempt to open the door if someone's in there. I told him to pack his bags and leave, but he asked for one more chance. I detailed the problem to him, again, in the Airbnb message system. I sent the whole stream to Airbnb through Twitter and had a phone call with them this morning. Airbnb agrees that with one more strike, violating our rules or making us uncomfortable, we will tell him to leave, and he will forfeit the rest of his payment to us. Airbnb will then cancel on his behalf, so we don't get dinged for that, and the room will then be open. One. More. Chance. That's it.
