Guido is the perfect host, he proactively contacted me as soon as the booking was confirmed, welcomed us, gave us tips about the city, and suggested nice restaurants. The apartment is very nice, spotless and very comfortable. It is located on the 4th floor of an historical building with lift. The location cannot be better, a stone's throw from Piazza della Signoria, Uffizi and Ponte Vecchio. You can easily walk form the station Santa Maria Novella if you come by train. Definitively recommended.
