Stayed at the apartment for a couple of nights. We're very happy that the host allowed us to check in a little early. The walk from Termini was only 15mins of dragging bags. Bus station directly in front of the apartment to the centre of Rome and all the sites and walkable if you don't mind walking.
Enjoyed the families restaurant below the apartment as it was convenient, reasonably priced and lovely authentic Italian food. The only downside was the potential for loud guests and outside noise. Was only a problem for a couple of hours on the first night. Very spacious unit, modern with all the amenities you need.
Washing machine a bonus. I would definitely recommend this apartment.
