This place was an excellent AirBnB rental for our group! The place was very clean, warm and inviting. We found it to be even nicer than the pictures describing the apartment.
It is close to the train station, and we just hopped on the tram back and forth to the stop that is very close to the apartment. It is maybe a block away from the front door to the metro stop, which was new and clean. The area is definitely more of a neighborhood of locals than the center of the tourist area, but we enjoyed that. You are just a few minutes from the center of the Florence's tourist area, while not in the middle of all of the people.
If you are considering a stay in Florence, we would highly recommend Caterina's place! She was very gracious, and we could not have asked for a better host!
