This room was a great value. It was clean and in a secure apartment building. We came into Florence by train, and there is a bus with a route that goes right by in front of this apartment. To save a little money, get the bus tickets in the train station rather than on the bus, and get return tickets as well since the apartment is maybe a 20 minute walk to downtown Florence.
The shared bathroom is like a hostel, so try to use it outside of peak hours if you want time to prep for the day. The are around 5-7 other people who will be using the same bathroom.
The price can't be beat if you are willing to share a bit.
