The three of us had a great stay in Samuel's flat! It was a perfect location right near the Duomo, which is convenient for everything in Florence, but it was quiet and a very peaceful place to relax after walking all around town taking in the sights. The air conditioning made it really comfortable even in August. There is a double bed and an upstairs loft for a third person. The four flights of stairs were not a problem in the slightest, and Samuel's friend was ok with our emailing her an hour before our arrival (we were coming from Pisa), which was really convenient for us. I totally recommend this flat to anyone looking for a comfortable, convenient place to stay in Florence
