Marzia's apartment is at an amazing location. You can see the Vatican basically right outside the door. The shower works well, the bed is comfortable, and everything works really well. It is as described and I really enjoyed my stay there. It's very close (about 2.2km) to the colosseum by walk. Which is not at all far, and as you get used to Rome you can actually short that. I was able to in one loop go from the apartment to the Basilica di San Pietro, the Castel Sant'Angelo, the Piazza Navona, the Pantheon, the Fontana di Trevi, Foro Romano (Forum), Trajan's Column, the entire heart of ancient rome, and the Colosseum. There's a really nice McDonalds near the Piazza Navona (between it and the Pantheon). The location is perfect.
