Great location for sightseeing and Francesco was very communicative. He even brought new linens each week I was there so I didn't have to do laundry myself. It's a charming flat with everything you need for a short stay.
With that said, I'm not sure if it was just during my stay but I would not exactly call this flat "quiet." It's on a busy street which can bring noise into the kitchen area and the shop downstairs played loud music that could be heard in the apartment from noon-10pm most days. Again, this could have been an anomaly but should be noted.
