Stayed in Federico's apartment for a week in June with the family. Federico's an excellent host and set us up with a private car from the airport, welcomed us when we arrived, showed us the apartment and have us a guide from the terrace on where local restaurants where located and how to get to public transportation.
The apartment is excellent for a family with kids, it's easy to get around and spacy enough so you don't get on eachothers nerves are a few days. And the view from the terrace is awesome. Ending a long day walking around in Rome with a glass of wine on the terrace is not a at all a bad way to end a day.
The kids (age 7 and 9) wanted to shime in and add to the review and said: super awesome best vacation ever!
