The flat is very well located and comfortable. We were 2 couples with small children. Since it's on the first floor we had to take the push-chairs up the stairs but they are not very high so it did not feel like a big problem. The decoration of the flat is quite specific so check the wall paintings to make sure you like the style. We did enjoy the fish tank and the cleanliness of the bathrooms. It is very central but in a quiet street, the restaurant next dire is nice as is the closest pasticerria.
Michele was available when we had small questions. The train station is quite close.
We would definitely consider going back in our next stay in Florence.
