My friend and I had a perfect stay at Roberta's place! The room was spacious and very clean with a very comfortable and big bed. The whole flat was very clean and tidy. It's approximately 25min. from the colosseum by foot. But you can easily get to the colosseum by bus within 10min. which is close to the apartment. Roberta is a super friendly person. The communication was fast and very easy. She prepared a great breakfast for us every morning and was always helpful and kind. I truly recommend her place for a stay in Rome :)
