The reservation got canceled. We were about to enter the apartment and someone was opening the door from the inside. Someone overstayed, but host didn't check. This someone left and left the apartment door opet and everything. Since we didn't know what was used or clean, when we contacted the host, both through a call and messages. In the end we had to call Airbnb Support and cancel the reservation, after more than 2 hours of wait. Nobody showed up and we were forced to find new accommodation on 09:30 PM on a Friday evening.
