We had a great experience at Concetta's place. We arrived late due to flight delays, and they were flexible in meeting us at a later-than-expected time to let us in. The apartment is just as it is presented in the photos. It's clean and has more than enough room for two people. It's not next to any of the major tourist sights, but it's only ten minutes from a Metro stop, which makes all of the sights easily accessible. The bonus of being away from the tourist sights is the neighborhood is quiet and easy to walk around in (no crowds). We also interacted with several of the neighbors, all of whom were friendly. We'd stay again.
