I only needed to be in Florence for a night between flights. This was a perfect layover. I took the airport shuttle (which runs every 15 minutes and costs around 5 Euros) to the train station; from there an easy three block walk to Carmine's place, and up a couple flights of stairs. Mine was a good sized room with a big bd. There are two or three others rooms he rents in the facility. The shared kitchen was quiet, but the shared bathroom was active. It also has a washing machine that was in use the whole time I was there. My room looked out over the Florence Central Market -- lots of shopping action by day, reasonably quiet at night. And an easy few blocks walk to the Duomo.
