You will stay in Pier's place, which was not ready for guests. He is lucky to live in an incredible location, which is the only plus. His house was dirty when we checked-in - dirty floor, dirty bathroom, trash still there, freezer with food, all of his belongings everywhere in the house, etc. His excuse was he wasn't the last to leave the place (whatever that means) and that the place was cheap compared to similar places around. Airbnb support didn't help us, so we decided to clean the house, because we couldn't find anything affordable (it was Monza GP). I hope he can solve things which isn't difficult, just need to pay someone to clean properly the house and keep all of his belongings aside from guests.
