We stayed for 2 nights which was perfect to see the most of Florence. the room was really nice, though a little bit outside the center but close enough to walk within 20min to the center. there are also cafés close by. everything was really clean and we had a lot of privacy. the entrance is shared but sleeping room and bathroom are separated from the rest of the appartement.
btw the public transport is really affordable and close to the appartement as well so you can go by tram to the center/train station.
all in all we really enjoyed our stay and would love to come back one day.
