My family and I had a good stay at Marco's place for 3 nights. His place was clean and spacious. He also provides a super handy mobile wifi.
Marco is extremely kind and made sure we knew where everything was.
His apartment place is conveniently located between Roma Tiburtina (stop you get off from the airport) or Monte Tiburtini Subway.
Tiburtina is a great neighborhood with tons to do. From Bakeries, novelty goods, cafe and Gelateria (Must try Lu Brano) within 2-3 min.
There's a small shopping center Tiburtina Shopping Center and along the street close by to center are lined up with full of espresso bars and bakeries that you should check out.
Another must try the local cafe for food (Marco will show you we forgot the name) right across the street. We probably enjoyed the pizza there more than we did at 5 star restaurants in the center of Rome.
Overall, it's a experiential local neighborhood away from the busy city.
