We had a great stay in this apartment! Although we were sorry we didn't get to meet Maria, her husband was a very gracious host and offered us some great advice - we took a lot of his suggestions! We were very comfortable, the bedroom ceilings were gorgeous and the location was perfect for newcomers to Florence (5 mins walk to Duomo, and 2 min walk to see Statue of David).
We can definitely recommend you stay here :)
