We just finished a week long stay at Daniela's flat in Florence. It was a wonderful stay! Daniela was incredibly communicative and gave great instructions for our self check-in (we appreciated the bottle of Chianti!). She also responded to messages quickly and was so gracious to arrange our taxi to the train station for when we checked out. From the window of the flat you can see the Duomo in the distance and it is an easy walk to all the main sites. The cocktail bar across the piazza from the flat is a nice place for apertivo (we went twice) and there are tons of restaurants within a few minutes walk. As a note, if you are a light sleeper or sensitive to noise at night, I would recommend earplugs because the piazza can be quite lively at times. It didn't bother us at all, but we live in a city over a brewery and a half block from a sports stadium so we are used to night noise :) I definitely would stay here again and will recommend it to friends traveling to Florence.
