Fernanda made us very welcome in her B&B, giving us tips on where to go and what to see, and making sure we were comfortable. We were in the big room, which was spacious, bright and clean, however rather noisy at night. If you're a light sleeper, better to request the sun or the moon room which are at the back of the building and are much quieter. The flat is located a little outside the tourist centre, but you can reach the Duomo on foot within 10-15 minutes. It's also a 5 minute walk from the train station, which is very convenient. It was a great base to explore Florence from, we highly recommend it.
