We were not informed as such beforehand, but we were met by a person other than the host. She didn't give her name. There was no tour of the apartment nor instructions on how to use the gas etc.
We booked four nights but left after one, as the listing with regards to the air conditioning, was inaccurate. There was no air conditioning on the first floor and the one on the second floor/loft was simply insufficient. It was not cool unless one was within a couple meters of the air conditioner. We informed Andrea of this our first evening and his response was only that it was a hot summer. Apparently, no guests had complained about the air-conditioning before - but we were very uncomfortable. We wanted to find a solution and so we asked for a fan and one was delivered the next morning. It made little difference however, and we then informed Andrea that we would be checking out that afternoon.
It was also a bit disappointing that the apartment wasn't entirely clean. The books and shelves were very dusty. Most of the kitchen cupboard doors didn't close properly. The 'dressing room' was a very warm walk-in closet.
We understand that Airbnb properties are not hotels but we have used Airbnb several times before and have had no issues regarding accuracies with listings. Fortunately, Andrea also wanted to reach an amicable agreement and we were able to enjoy our holiday in beautiful Rome.
