Barbara's place is in a nice neighborhood on the north side of Rome. There is a great pizzeria across the way and a big park nearby. It's a great value in a lovely, non-touristic neighborhood. We enjoyed our stay and were able to walk to a lot of places.
It wasn't very clean though. There was loose hair on the floor of the shower and on the towels when we arrived. The floor was a bit dirty as well.
Can confirm that it is a bit loud at times since it is a ground-level apartment. But weeknights and days without construction are fine.
