We really enjoyed our stay at Giovanni's place, it's very nice and spacious. Check in was very easy, there is AC is both bedrooms which was much appreciated considering the heat in Florence. Communication was also very easy and quick - only thing is that the apartment is not exactly in the centre of the city so it is a bit of a walk to get to the historical sights and galleries. Considering the size of Florence, however, it is not an issue - it took us a maximum of 30 minutes walking to get to our destinations.
