We (a family of four) had a really good experience at Andrea's apartment. He was there to welcome us and called taxi for us when we were heading to the airport. He was helpful and very responsive. The apartment is clean and modern and the location is great. There are some bars and restaurants down below and people seem to hang out until late hours in the street and be a bit noisy. But that's what you get for being in a center right next to Colosseum.
