A great spot for one person or a couple to spend 3 or 4 days; I stayed for 3 1/2 months. A two minute walk to Santa Croce -- the apartment is located on a quiet street where one can rest, but close enough to the Florentine action that one can walk everywhere. Also, the street the apartment is located on is dotted with little restaurants.
As far as the host, one could not ask for a better, more attentive host --Tiberio is great! And so is Signora Donati who would be your de facto supt. All in all, one cannot go wrong staying at this place. One thing: A lot of stairs, but very manageable -- highly recommend.
