Valentina arranged for her companion Alex to pick us up at the Rome Int'l airport (were we dropped off the car). He also took us to the airport for our early departure. The cost is less than a cab for door-to-door service with Alex's gracious, informative, and funny conversation. He oriented us to the apartment (that's in the same walled garden complex where they and a few other families live) and the area. They provided written restaurant and shopping recommendations that were helpful. The apartment is within blocks of the Coliseum, the Forum, the Palatine Hill, a Metro station, and local restaurants. And walking everywhere else (e.g., Vatican Museum) was easy because Rome is as good as Paris as a walking city, perhaps even better because it's not as large. My wife and I highly recommend these hosts, their apartment, and this area.
