Massimo's flat is great! It is situated centrally to all the popular tourist spots (less than a block from Mercato Centrale, only 5 minutes' walk to the Duomo, 15ish to Ponte Vecchio), as well as being only a few minutes' walk from SMN train station. The apartment itself is quiet, clean, and we were very happy to learn there was plenty of hot water (not always the case!!) and the AC worked very well. Check in and out was very easy, and there was a great guidebook that had every kind of recommendation you could ask for. Looking forward to hopefully staying at Massimo's flat next time we're in Florence.
