Location is perfect (right around the train station, short walk from the city center). Flat is actually darker than on photos (only 2 windows in the bedroom). As described by some people earlier and Niccolo himself it's a little noisy- street is busy (cars and buses during day, people from nearby bars and restaurants during evening and night), so better take your earplugs. Besides that everything was fine and it's a good place for a quick stop in Florence!
