This Airbnb is definitely up there as one of the best I've ever stayed in. I did not meet Filippo, but instead was primarily in communication with his mother, Sally. Sally met us in the apartment for check-in and showed us around. She is English and therefore communication was a breeze for us Americans!
Some of the highlights were the well-stocked kitchen, two bathrooms (both with showers,) and the terrace with a beautiful view overlooking Florence. The apartment is located in Florence's historic city center; all the major tourist attractions were just a short walk away.
I stayed in the (I believe recently added) third bedroom. The ceiling in that room has a steep slope from the headboard to the end of the bed, giving the room a very cozy, comfortable feeling. The bed in this room was a bit firm but I found myself to be more comfortable than I expected during the night.
Overall this was an amazing place to stay. I recommend this listing to all!
