We had a nice stay at Filiberto's place! The apartment is a bit darker than displayed on the images and has only one window. Everything was nicely prepared for us, but the kitchen and bathroom could have been cleaned better. I wouldn't say it was extremely dirty, but a bit filthy. E.g. the handles of the kitchen shelves were sticky and there was still hair in the shower.
Nevertheless, the apartment is in a perfect location! Very alive an hip neighborhood with bars and restaurants, and even the Duomo is only a 20 min walk away.
