We had a very nice stay in Firenze.
Communication with the hosts was great with tips to visit the city, restaurants, bars but also good indications about how to get to the flat regarding the transport.
The flat is ideally located, in a neighborhood that's more local than touristic, all while remaining close to the city center and famous spots (10-15min walking distance).
The street is pretty calm, and anyway the flat has good sound-blocking windows.
Thanks Gennaro!
