Mamo's place is great! He met us at the apartment to let us in and show us around - a wonderful personal touch that you don't always get with Airbnbs anymore.
The location is in a little Piazza with lots of energy in the evenings and plenty of good restaurants just steps away. It can get a little noisy from the street if you prefer the quiet, but if you close the windows you wont have any problem at all.
It was easy for us to walk to all the sites we wanted to see and even get some necessities when our luggage was lost by the airline.
I would definitely recommend this listing to anyone traveling to Florence.
A note - it is an old building with lots of stairs to get to the apartment. A consideration with anyone with mobility issues.
