Lorenzo is an excellent communicator and very helpful in every way. His place is gorgeous! The hallway leading up to the apartment is well appointed/furnished and interesting, and then the unit itself is shockingly large and nice. The AC is super powerful (if you want it to be), the deck is enormous, and the apartment is a nice retreat from the bustle of Florence.
The location is just incredible. When you walk out, you literally are looking right at the Duomo to the left, and I don't think you could be closer to it unless you stayed inside of it, which you obviously can't. This location is really nice for more than just the Duomo. It's a short walk to the other side of the river for great restaurants, and to the famous shopping bridge.
Highly recommend you stay here. Also, the laundry is a real thing and totally awesome. You have to hang dry, but there are lots of racks you can bring into your room and that doesn't take more than a day or so.
