Roberta's place was excellent! The check in process was smooth and Roberta took time to point out our location in proximity to the major areas of the city. Her map was crucial to our time in Rome. The flat is so well decorated and cute! It's in a great part of town (there were cafes, bars and gelaterias all around). It is literally a block from the Colosseum and off a major road that leads you on a direct walk to all the big attractions. It's about 25 minutes from Vatican City by a very easy bus ride. Great, great place to stay!
