We were very happy with our stay at Gianmarco & Antonio's flat. The flat itself was as displayed on the pictures and we really appreciated that it was equipped with AC. Only downside was the location which was close to the Centro Storico but not exactly what we were expecting. We didn't have any issue or anything but you need to walk a little bit to find some nice restaurants/coffee shops. Also be aware that the flat is on the 4th floor so it's quite a lot of stairs... But overall our experience was good - the check-in/check-out process was easy and the host was very responsive!
