When we arrived, the host said our room was occupied by someone else. He offered another room not far away from the prepaid one but it was not acceptable as the new room is located above the host's restaurant. The restaurant is open until 2-3 a.m. according to google maps. And even at daytime we heard loud voices of restaurant personnel as they work literally in the next room.
We were not happy with alternative room and according to Airbnb policy we asked the host to cancel the booking but he refused to do so. And if we would cancel the booking we woukd loose 190 USD. So we spent several hours to make the host cancel the booking, including communication with Airbnb help&support. We had to urgently look for a new room at 9 pm.
