Mario was a great host he was in time to receive us and also explained us little bit about Florence, which was great. The house itself was very clean. The common kitchen was well equipped, although we did not cook much but there were basic facilities. There was also a nice garden in the house. The bathroom was shared one, but there were two in the floor. The location was close to the central station, 10 mins in bus. The historic center itself is around 10 mins walk from center. We stayed there for two nights and could also visit Pisa and Clinque Terre.
