We very much enjoyed staying at this incredibly historic and beautiful flat. You truly feel that you are living in 15th century Florence. The patio was a definite plus and the views from the windows/patio were amazing.
The location is on point. It is steps away from a ton of restaurants and bars as well as walking distance to the Ponte Vecchio and Piazzale Michelangelo (10 min walk each)
If you're going during the hot season, take a bug spray with you as there are a lot of mosquito that eat you at night.
The flat is on the 4th floor (I think) and there is no lift so don't take big luggage with you.
We recommend Francesco's place to anyone who is visiting Florence! Ciao!
