My partner and I stayed in Roberta's place for 3 nights and found it to be the perfect place to base ourselves during our time in Rome.
The location is perfect and is within a 10 minute walk to the Colosseum, along with being walking distance to the train station.
The apartment itself is perfect for a couple and was very clean and well presented. It is located on the top floor but there is a lift which makes it very easy to get your luggage up there.
Roberta was a great host and made it very easy for us to communicate with her. She also was incredibly accomodating with our arrival time and made the check in and check out process very simple for us.
We would highly recommend to anyone visiting Rome and would definitely stay again!
