Very nice apartment where you can actually see the Colosseum from the lovley terrace. One separate bedrum with private exit to the terrace and two large sofabeds in the spacious living room was perfect for us (you could separate the two sleeping areas in the living room with a curtain). The terrace was the best part, the view was really nice and we spent at lot of time there. The location was great, close to restaurants but without the noise from night clubs. We heard that the area close to Colosseum could be a bit rough, but we felt perfectly safe.
One super market (Carrefour express) really close and a larger one (Coop) in walking distance.
Willy was an excellent host, he provided advice for us and helped us with transportation to the airport.
