I can almost just confirm and repeat, that the previous guests are already wrote: it is a perfect little place, cozy, silent and clean. It is not in the city centre, but the public transport is very good, four buslines stops near to the apartment, and bring you to the historical centre. I lived in Chiara's place for one month, and I can also confirm, that everything was by hand: supermarkets, shops, news-stand (where you can buy tickets for the local public transport).
Chiara was a really nice host, always answered my questions quickly, which made me feel comfort and safe about my journey to Florence. It is a perfect place if you don't want to be in the noisy centre and I can offer it for longer stay as well. It was a good background for my one month research work in Florence. Grazie mille Chiara!
