Maria and her daughter Rita are very welcoming and nice hosts. The apartment is in a great location, near the Vatican and walkable distance to the downtown. The apartment was clean and pretty comfortable to stay. We stayed for almost two weeks, and have no complaints. There were lots of helpful stuff for cooking at home and just feeling comfortable, even coffee was there for us.)
The apartment building is located near in the corner of the road, and restaurants, bars, so it may be a little bit nosy during the weekend (although we got used to it). The host let us check out later and kept our luggage for a couple of hours before our flight.
I would definitely recommend staying here.
