We had a wonderful stay at Benedetta's apartment near Piazza del Popolo. We had an unusual situation with my wife and I there for a few days, and our two daughters joining us at various points, but the apartment turned out to be ideal for our situation.
The real advantage of this place is the location. It's on a quiet side street but a few steps to Piazza del Popolo and the metro in Flaminio, and an easy walk to Piazza di Spagna and Piazza Navona.. The apartment itself is clean and very comfortable, ideal for a family of five or six. Communication with Benedetta and her crew was on point, and Sergio was particularly helpful when we moved in. All around it was a top-notch experience.
