Alessandro's place is GREAT! It is centrally located, right around the corner from the Duomo. Everything is easily within walking distance. The apartment itself is much bigger than I expected, which was a great perk. My partner and I stayed for 3 days and this was a perfect space for us, plenty of room, very clean, and stocked with everything we needed. Alessandro allowed us to check out an hour later than planned so we wouldn't have a large gap in time before our train - that was greatly appreciated! Also super close to the train station and anything else you will need! I'd highly recommend staying here when in Firenze.
