We had a great stay at Cristiana's apartment, it was in a great location easily walkable to all the main attractions and the train station. We arrived earlier than anticipated but Cristiana was able to let us in quickly and gave us some great recommendations, she even contacted us during the trip to make sure we were ok in the heat! The apartment really is in an ancient building complete with wooden ceilings and stone steps. There was some noise from the street but not terrible and the shower isn't the best but we managed. The terrace was great for breakfast (and provided a great background for pre-night out selfies!) would stay again if I'm lucky enough to return to Florence!
