Lorenzo's place was overall great - nice interior, 2 bathrooms, and has a ton of space! The building had an elevator, but do note that there were a few steps (maybe 3-4 steps) leading up to it. The location was good as well- very central to a lot of attractions: about a 10 minute walk from Firenze train station, less than five minutes from the Duomo or the Uffizi gallery, and very close to shopping and food options (try All'Antico down the street).
I also appreciated how easy and detailed the checkin instructions were. Lorenzo was also very accommodating as a host.
