This is an excellent, spacious little studio VERY conveniently located to some of the most popular parts of Florence while still being a bit hidden and off the beaten path. You can sleep quietly but be at the Ponte Vecchio within minutes. The room is well laid out, with ample storage space and a nice, small kitchenette; you won't be cooking banquets, but snacks and light meals are well supported. About the only qualms I'd have with it are that its location on a small street makes it very dark, and the hot water heater barely supported one shower.
Other than that, a well laid out and cozy apartment well suited to a couple and with enough space for three (if that's allowed). Francesca and her son handled the rental professionally.
