Marco & his apartment are wonderful. The place is as nice as it looks in the photos & Marco goes above and beyond to make sure all your needs are met. It's like having a personal concierge! He had great suggestions on restaurants and traditional Roman recipes we needed to keep an eye out for. Since our Italian is not very good He even made a reservation for us at a particular place we wanted to try.
And the location of the apartment is great. Quick and easy to get to/from the airport, about a block from the Circo Mossimo station, walking distance to the major landmarks and the Trastevere neighborhood. Really it's all you can ask for.
