Location is great as it is a short walk to many attractions in Florence, including SMN for your arrival/departure. There are good restaurants and cafés on the street and a grocery store a couple of blocks away. Communication with Irene was good, even when I messaged her by mistake.
We gave a 4* for the relative dampness of the apartment (which may have been because of the time of year), the water pressure in the shower wasn't very strong, the overall space felt tight for our stay, but that could just be us and what we're accustomed to.
We enjoyed Florence (our 3rd time here), and this Airbnb allowed us to be close to the action to come back and refresh during the day.
