This is an excellent apartment in the center of Florence. We had a very comfortable stay with 6 adults. There is air conditioning although we did not need it. Although we were right in the center just a short 2 blocks from Piazza della Signoria, there was no bar on our block so it was pretty quiet at night. We were easy walking distance to all the major sites — Santa Croce, Ponte Vecchio, Pitti Palace, Duomo, etc. Host was very responsive and gave good suggestions for places to eat and local specialties. They also came out to find us when the taxi driver from the station left us in the wrong place!
We would absolutely stay here again.
