When we arrived security wouldn't let us in because he wasn't informed about the reservation. He also told us that the room was not ready and uncleaned because they didn't expect anybody (we booked about a month ahead). The host could not be reached for several hours and we were stuck waiting in front of the building for 4 hours. In the meantime we contacted Airbnb and eventually had to move to a different booking. After the move the host told us that there was a problem with the cleaning lady which still doesn't explain why security wouldn't let us in. We would have taken the room in any condition as we were already traveling for over 15 hours.
