Our stay in Firenze was great but alas, too short. The flat is in a great location right up from the Duomo and very centrally located. It was off to one side so it was not constantly busy or crowded. We were right around the corner from the Accaddemia where Michelangelo's David is at.
Bruno is the one that met us ahead of time and let us in. We arrived close to around 1700 so we still had light out to get a good understanding of where we were at. There is a grocery store next store and we easily walked to the train station. We had four kids with us and they walked just fine (even amongst the crowds with luggage).
We would stay again and the only recommendation I would make is to invest in some new bath linens. That is being somewhat picky and it would not stop me from staying here again.
