Amazing apartment. The location is perfect to the main touristic places (i.e the Duomo, Palazzo Vecchio and Ponte Vecchio, Uffizzi, etc). We definitively recommand to stay in Gabriel's. The communication was very good, he's reactive and gave us tips about the city (restaurants to eat, fountains, marketplace).
The flat is like the photos, we had a great time. In these hot days, the AC was life-saving. We did appreciate that. The street next to the room is sometimes noisy but that's OK since we're in the center of the city.
We totally recommand the apartment!!
