Ciao! We stayed at Guido's apartment for 5 nights and it was lovely and he was more than accommodative. The apartment was in a great location just a few meters from Santa Croce, but also close to the centre of Firenze. The apartment is on a quiet street and has a nice size bedroom (with air-conditioning!!! we were there in July...) and a living room and working kitchen and nice bathroom. Would definitely recommend for future visits to Firenze!
Ciao!
