Cozy place, perfect for two in an unbeatable location. We were in Florence for three days and thankful for this apartment as main base. It was so close to everything that we used it as a mid day rest stop after walking all day, before venturing out again for the evening.
The apartment has lots of amenities - we especially appreciated the washer, it was tiny but more than enough space for our laundry of few days. The weather was hot during our stay, however, we did not miss the air conditioner, as the fan in the bedroom kept us comfortable.
The only possible drawbacks about the apartment would be the narrow layout of the bathroom, where the space between the toilet and the wall are so close, that a tall person might need to do a little maneuvering before settling down, or simply sit sideways like I did. The kitchen also lacked the necessities to cook (no salt, sugar, oil), however, we were not in Florence to cook. I did use the hot plate to make tea and it was super easy. There is a faint smell of wine cellar or basement, it is tolerable with the windows opened. For us, none of these were deal breakers.
To sum it up, we had a great stay. The host was extremely responsive despite being out of the country. Her father who greeted us was a total sweetheart.
