We had an amazing stay at Gianfranco's apartment.
The flat has an old florentin style that nicely fits with the general atmosphere of Florence. + Very clean, comfortable, fully equipped - we did not need to bring anything.
The location is central (5 min by walk from Ponte vecchio) thus a bit outside of the crowded areas.
The only negative point was that we could hear people chatting loudly in the street at night, especially during the weekend.
Gianfranco and his family are very welcoming and helpful. Communication is easy. They explained everything we needed to know about visits and restorants. + The bottle of Chianti was highly appreciated !
In brief, stay beyond expectations !
