Location is absolutely perfect with it being just opposite the academy. It's no longer than a 25 minutes walk from all of the sites in Florence and also the train station (we took advantage and spent some time in Rome, Pisa and Siena).
The flat looks exactly like it does on Airbnb.
Fede was lovely and greeted us when we we arrived and helped us find our way to the flat. She was also always there to answer any questions that we had. There were groceries in the kitchen as well for us to use and a handy guidebook with advice in our room which was a nice touch. The bathroom already had amenities in it as well which we weren't expecting.
There are too many good things to not about this home, we loved it and are sure that you will too.
