We (2 families with 4 adults and 7 children) stayed for one night in this nice flat. It is in the "middle of the middle of the center" of Florence so everthing is nearby (sightseeings, bars, restaurants). As we travelled in August we where very happy about the good airconditioning. The flat was perfect for us, because every family had their own space with separate bathrooms (4!).
The owner and our host was very helpfull so we had a nice and easy move-in and move-out.
I think the flat is a perfect opportunity for everybody who is looking for a nice place to stay in this wonderfull city!
