We have spent 3 weeks at this apartment at the end of August and beginning of September 2017. We were only two adults but the apartment would be perfect for a family of 4.
The apartment is exactly as seen in the pictures and actually feels a bit bigger than anticipated. The air conditioning was a must during the heat wave we had for our first 10 days! The apartment was extremely clean and the neighbourhood is very calm. It is just far enough from the center to give you an authentic feel of Florence. Not the place if you are looking for night life and party. Very little tourists in the area but it was easy to get service in English. People were very nice.
Lots of little shops, cafes and restaurants around. All are very good but we especially liked the Cavani gelateria ( a must try - established since 1927) and the aperitivo at Caffe Lorenzo. It is generous enough to be your dinner! Two supermarkets to get the food you need but we ended up buying from the pasticceria, salumeria, etc separately. If you are intending to cook a lot, the kitchen is well equipped with pots and pans and dishes.
We would recommend this apartment to anyone looking to spend a calm and authentic Florence vacation. Definitely worth it!
