Leonardo is a charming and helpful person who did not hesitate to work up a sweat (literally) to help us catch a bus when we left to the train station at Campo Marte.
Otherwise the apartment is spacious and well furnished, close to the center as indicated and the Oltrarno. Thus, every Firenze's must sees are in a 15 min. walking distance.
Last but not least, the place is quiet and the balcony really pleasant.
