I highly recommend to stay at Giulio and Flo's place. It is central, walkable from city center, ponte Vecchio or the train station. The room is well equipped, clean and convenient. Downstairs at the street corner a nice cafe for a drink, breakfast or a glass of wine. Giulio works very close to the apartment and can help you very quickly, if you need anything.You can have a breakfast at the place in the morning, or enjoy a local wine at night.
I loved it!
