Our stay at Stefano was very nice. The place is clean and quiet and within the very center of Florence. Thanks to his descriptions we knew how to get there, although it was a bit hard to get there by car as the recommended parking garage is also within the heart of Florence. At your 3rd try we ignored all prohibition signs and then it was easy to find. Police also did not bother.
So we definitely recommend this place and will try to book it again once we come back.
