First off: two things which might be a deal breaker before you book.
The place DOES NOT provide breakfast. It says in the listing that it does, but it doesn't. It is a room rental, not B&B. So if breakfast is a necessity for you, look elsewhere.
Also, if you're not traveling as a couple, don't book because the bathroom has no privacy. It's completely open to the corridor of the room and even if someone answers the door you are in trouble. We had earlier booked it with a friend, she ended up cancelling else it would have been tough to spend a few days in Florence.
Good points: away from the tourists, TV has Netflix, room is clean and spacious.
