We had a lovely time staying at Cristiano & Valerio's flats we were a large extended family, and the flats worked out great everything was as promised and if there was any discrepancy it was fixed immediately. It is right in the center of Rome, close to all public transportation , you will definitely feel like a local.
Highly recommend using all of their advice they helped us arrange sidetrips outside of Rome and all were wonderful.
We will be coming back.
