The place is a gem. Charming touches. Good views of the Arno and the hills. Had a dishwasher and washing machine. Easy communication with the hosts. Plenty of hangers and closet space. The air-conditioned was fine. The internet was fast for casual browsing.
Quiet except for the occasional municipal garbage truck or ambulance. It's on the top floor, up about 50 stairs (no elevator), so it's insulated from the noise a bit. I had a great stay and I'd stay again!
