Great apartment in perfect location, 5 minutes walk to the train and bus station and 10 to the centre of Florence with all the major sights. Lots of great restaurants around. Lots of stairs to walk up as mentioned but they were really no bother and worth it for the view at the top and how quiet it was. The building is on a busy street but there is no noise once you get to the apartment. Really easy check in process, Sofia met us with keys and showed us around and was really helpful when we were late due to a delayed flight. Fast communication from Cosimo. All round really good experience, would definitely recommend!
