We had a great stay at Tommaso's place. The apartment was spacious, clean modern, and the location was absolutely perfect - right by the Ponte Vecchio and within walking distance of all the sights. We had some trouble finding the place (our fault not Tommaso's) and his father came especially to meet us where we were and bring us back to the apartment. I couldn't recommend this apartment any more highly. If i'm ever back in Florence, this would be my first choice to stay.
