Excellent location. Walking distance to every tourist place in Florence and good restaurant. WiFi was great. Place was clean and exact as described.
Downsides include no elevator (common in Europe it seems), and situated above restaurants means it gets noisy very early in the morning (around 6am) everyday. Early morning noise was very loud as restaurants below were setting up which interfered with sleeping in to get over jetlag. On our last day, we asked Stefano to book a taxi for us to take us to the train station. He happily obliged and confirmed the night before but the taxi did not show. When we asked Stefano to call the taxi company again, he asked us to wait 10-15 more minutes before calling him again - which was cutting close to our train time, so we had to trek to the train station on foot with 6 luggage's which was not pleasant. Just to compare, another airbnb host in the same building met with her clients personally to ensure they got into a taxi. She then helped us to call a taxi as well, which by then would've taken too long to arrive. The point is to book transportation in advance to train station/airport as taxi may be hard to come by and Stefano may not be as responsive nor able to help.
