We had a really nice stay at Marina's apartment. Everything was perfectly in order. 5 minutes walking distance from the train station, Marco was there to greet us and showed us all the information that we needed. You can find basically everything (groceries, shopping, great restaurants etc) all within a stone's throw away. It is a very nice and vibrant neighborhood but you don't hear anything inside the apartment. I highly recommend this place and will definitely stay here again the next time I come to Florence.
