We stayed two nights at Roberto's place, which is located in a side street of a high-traffic road. The appartment is small but we found there everything that has been advertised on Airbnb. The appartment is located just below the roof, which makes it pretty hot in summer. Aircondition is available, however opening the windows was not a good idea due to traffic noise. Nervertheless we can recommend the place, it's a good location for exploring Florence.
