Sergio is a great host, very patient and friendly. The room I stayed in had plenty of space was very clean and overlooks a lovely park. I really liked hearing the church bells toll in the morning. In my opinion the flat location is ideal for anybody looking to explore Rome. It even has a bus stop right outside the front door! Other transport links are very close by as well and there is a lovely pizzeria place on the corner and a coffee and cake shop just across the street.
I really enjoyed my first trip to Rome and will be looking to return and no doubt stay at Sergio's again. You just can't go wrong with this place.
