Lorenzo was super nice to us allowing us to check-in a little earlier than scheduled. The front door is a bit unusual in that you have to turn the key many times to unlock. We contacted Lorenzo and he promptly responded and explained how the lock worked, even offered to come by. Upon entering, we very quickly settled in to his lovely apartment which was very clean and comfortable. Most of our trip it rained, but it was so nice to come in and have a cup of tea. Lorenzo had graciously provided tea and a few other little extras. The building has an elevator which is terrific since the apartment is on the sixth floor. The location is ideal. It is not a far walk to many restaurants and shops.
Although, we had never been to Florence before, I would recommend staying at Lorenzo's place if you are in Florence!
