Our host was there when when arrived and showed us around the apartment and how things worked. She was very charming and friendly. The apartment was exactly as described and photographed. It was a delightful place to spend a few days in Florence.
The location--Santo Spirito--is close to everything but away from the most tourist-populated areas. It is always the area we stay when we come to Florence. We will try to stay in this apartment next time we come to Florence.
