I enjoyed my stay here. It's conveniently located around 5-7 minutes from the train station, and since Florence is not huge, getting to the city centre takes 15-20 minutes walking.
For the check-in Mr. Roberto greeted me at the entrance and took the time to tell me about amenities near the property and go through the furniture/appliances instruction and additionally giving me some local tips both about things to see and eateries.
The walls don't seem too thick, so if some of the neighbours are loud you do hear them, but likely this hasn't happened late in the night or early in the morning, just something to keep in mind if you want to stay in a space that is more soundproof. I would stay here again if I was in Florence.
