Tommaso waited for us in the apartment and give us a lot of useful info. We went to the restaurants he mentioned and was great. The pizza we eat at the "Il pizzaiuolo" in Firenze was delicious!
The apartment is awesome, has everything you need, is in a quiet area, 15 min by tram. to the central station in Firenze. From there 10 min walk to the Duomo.
There is a supermarket just across a roundabout from the apt. So you can buy what you need.
Highly recommended!
