We had really a great stay at Vittoria's place. In a few words: clean, quiet, spacious, located in a nice residential area and with a great host to welcome us.
We arrived very late, due to a problem with our flight. Vittoria has been a great host and very supportive, even though the plane was 4 hours late. We arrived past 1AM at her place, and yet she was there, giving us a tour of the apartment and giving tips to make our stay in Florence better.
The apartment itself is very comfortable, big, with every amenity available (wifi, air conditioning..). Everything as described and corresponding to the pictures. The place was also very very clean.
Location wise, it's relatively central. We basically walked everywhere (we stayed there mainly for a concert in Visarno Arena and it took us about 40mins, while to reach the city center it's about 15/20 minutes by walk). You can, however, also catch a few buses and, most importantly, it's not in the traffic limited zone of Firenze (that can be a nightmare). There are therefore many parking spots nearby (even a few free ones). All in all, I would visit again and I recommed any fellow traveller to stop by! You will not regret it!
