Great location by one of the must important and historical piazzas in Florence: Santa Croce. A lot of wonderful "trattorias" around with excellent food. I recommend make a reservation for the best because otherwise you dont make it! Walkable distance to Piazza dell Duomo and to other important highlights is Florence.
The apartment is in a second floor, so be ready to carry your luggage up hill or be light!
At night the apartment is noisy because the neighborhood is trendy and crowdie...
