We had good time staying at Lorenzo's. Lorenzo is a very friendly host, gave us a lot of privacy and let us cook in the kitchen every day. It was a pleasure coming back to his flat every day after exploring busy piazzas of Florence. However, the room is on a mansarde, so if you're scared of climbing to the bed/ claustrophobic, you may suffer there. The flat is located about 20 min by bus from the main tourist attractions, but is very close to the airport
