I had an amazing time at Fabio's place. It was clean, spacious and quiet. Fabio was very nice and accommodating - my flight was delayed so I ended up checking in very late (around 12AM!) but he was understanding and came to let me in. I later moved to another apartment in Florence, for which the check-in was later that day, so again, Fabio allowed me to have a late check in.
In addition he was very responsive, and the apartment is in a very good location.
