The hosts were very nice and helpful. Easy and quick communication. The apartment is located very centrally (1 km to Ufizzi) but in a bit more quiet part of town, which we really appreciated. There are plenty of places to eat, and the best galateria in Florence close by.
The apartment is on 3rd floor without elevator, it wasn't a problem for us, buy may be for some. It was also very hot in the bedroom.
We loved it there and I would recommend for staying in Florence.
