An excellent location in the heart of Florence. Climbing up the stairs to 4th floor may be an issue for those carrying a lot of luggage but that was always well informed.
Silvia was very accommodating and even shared her personal number for better communication since we were not sure exactly what time we will be able to reach for check-in. She even personally came up during the time of check-in explainign each and everything.
Apartment was very clean. The shower area is a bit small so may be an issue for tall or bit hefty people. Overall quite satisfied with our choice.
