We had a great stay in the Green Apartments. It was a nice location, very close to the Colosseum. Andrea arranged a taxi for us from the airport and his assistant welcomed us and explained where the major sights were and how to take the metro if we wanted. She was very helpful, giving us good options for the two days we were in Rome. Great place to stay, would do it again. Felt safe, and it was nice and quiet. Just remember the Vatican isn't open on Sunday!
