The apartment is in a perfect location. Walking distance from the main attractions. The square downstairs has reasonably priced cafes, bars and restaurants. The market is slightly overpriced. Think you are better off just eating out. We paid 1€ for a tomato.
Anyway, the host are very welcoming. They left us coffee and biscuits for the morning. The apartment is fully equipped and stunningly designed. The bed was comfortable and because the apartment overlooks the courtyard it's nice and quiet.
We would definitely recommend it and go back if ever in Florence again.
