I had a great stay in Lucia's apartment. The apartment is in a great location, close to Palazzo Pitti, a less than 10 minute walk to Ponte Vecchio. I stayed here for 4 nights with my boyfriend. The apartment is cozy and perfect for 2 people. Everything worked fine and the apartment looks just as described and shown.
I would definitely stay here again during my next visit to Florence. Also to note, the apartment is at the top floor of a walk up building, therefore if you aren't in great shape or you if you've just walked up all the stairs of the Duomo this could be a bit much for you.
