As described, Roberta's place is only a stone away from Colosseum. It is on a street with many restaurants and bars and near the metro station and Carrefour supermarket. it was great to walk by and see the great Colosseum at different times from morning to evening. Roberta speaks little English but is a very nice and responsible host. She greeted us on the street while we were looking for her apartment. Otherwise we would have been lost a bit. She stocked up milk, juice, fruit, pastry, and cereal for the guests. Her 2 bedroom apartment is spacious. The pullout sofa in the living room made an extra full bed that comfortably accommodated our family of four. She managed to give us tips on touring the city. The best part was that she even arranged a car service for us to go to the airport on the way back. Considering most of the taxis in Rome are compact sized, the driver's Audi A6 was a rare luxury and most importantly could fit all of luggage.
The main bedroom and living room face street. The noises from the traffic on the street and patrons from the bars and restaurants were quite disturbing for somebody like me who is sensitive to noise. It could last to way over midnight and start very early in the morning. But it was not an issue to my family. Maybe that's a problem for all the apartments in the city. Other than that, everything else was great! We had a nice stay at Roberta's place. Thanks!
