The flat is in a great position and makes it easy to reach all the interesting places in the city. it is not for everyone though because in order to reach it you have to climb some very ripid stairs (no elevator) until the 4th floor.
Some things in the apartment are ruined (es. the door in the main bedroom doesn't close well and the kitchen sink has some troubles too) but the beds are ok and you have all the basics provided.
I don't think that this is usual, but we had some communication issues with the host, since we tried to reach her during our stay with Airbnb and she never replied, so we tried by phone and we found her. By phone she accepted our request of a late check out (4 pm instead of 12), but when the check out day came she called us asking to leave the house immediately (it was 12.15). This was really annoying, because we were buying the tickets to visit the cathedral and never did, having to come back to the apartment to pack in a rush.
