Michele (Michael) was the perfect host! He went out of his way to meet me late, when I was delayed coming into town, and gave me a full description of the area.
The apartment was a bit smaller than expected but would be perfect for a solo traveler on their way through Florence. It is on the ground floor next to the entrance to the building, so you do get some extra noise from that. However, the tenants seemed to be quite respectful of that fact.
It is maybe a 10-15 minute walk to the heart of Florence and only about 5 minutes from the Duomo.
With a few local shops and bars nearby this was a perfect apartment overall. I would definitely consider returning for another trip!
