Marcella's apartment is in a great neighborhood, just a 5 minute walk from the must see Piazza Navona. There's a popular bar (Bar del Fico, apparently one of the hottest places in Rome at the moment) just downstairs. We felt like we got the local experience staying there. All the major sites were walking distance away in either direction. Also, Marcella was very accommodating and let us check in early as our international flight arrived at 9am. She also went out of her way to buy a power adapter for the apartment when we asked her for one. Can't recommend this place enough!
