@Caroline74 If your review is posted, so is their review, right? You could make a comment on their review. Some hosts look at the guest reviews of hosts when deciding to accept a guest. Of course if they use IB then the host will not be alerted.
If you think their behavior is especially bad, then you would report it by flagging the guest. If you had expense to repaint the wall, that would be claimed in the Resolution Center.
From your description it sounds like tipsy behavior not terrible damage, right? I can imagine having a glass of wine in my hand with my arm propped up on the back of the couch and spilling wine, although I prefer white so no damage...:) good luck!
