Florence is a very walkable city, and Giovanni's place is excellent for those who want to explore the city that way. We walked at most 15 minutes from his place to get to all our destinations (Duomo, Firenze SMN, Pitti Palace) and the Uffizi Gallery was right next door!. There were plenty of restaurants and cafes within a 5 minute walk which made our stay that much more enjoyable.
The accommodations were great, although the Wi-Fi only worked in the main living area. Also, if you stay here, make sure to turn the water heater switch on.
Giovanni was very accessible when we had questions and helpful giving suggestions of where to eat and visit. My wife and I really enjoyed our stay here.
