Amazing apartment in the heart of Florence. The apartment is on the 4th floor, so be prepared for lots of stairs, but you get a great view of the Duomo on the climb upstairs which helps! There is a grocery store directly downstairs, and you are a quick walk from all the main sites and the train station. The street downstairs has many shops and restaurants, but the apartment is amazingly quiet since none of the windows face the street.
The apartment itself is small, but has everything you need and it is very clean. We would recommend Marco's place to anyone staying in Florence--seriously, the location does not get better than this!
