This is an excellent place to stay. One reviewer mentioned that the room is smaller than it looks, which is true. It is really just the size of a hotel room. But, it is just amazing how they have managed to fit everything you could need into that little space (silverware, plates, pots, toaster, fridge, coffee expresso, tourist books, tv, etc...) !
And it is virtually at the base of the Ponte Vecchio, with a grocery story, laundromat and bakery right outside the street door. You don't have to walk all over the place to get what you need. So, if you are exploring Florence, you can just easily take a break from sightseeing and rest for a while, since the apt is right there in the thick of it all.
On top of all that, it is amazingly quiet. You can roll down the shutter to have complete darkness, so you can get a good night sleep. Taxi's also come slowly down this street all the time, so it is easy to flag one down. We had one of them drive us to the bus terminal, where we could catch a bus to Venezia Mestre when we left.
