We were a family of 5 (kids 6, 11, 13). The whole family was very satisfied with the stay. Excellent location - we walked to all sights (Pantheon, Vatican, Colosseum, ....)! Surroundings very nice with lots of really good restaurants (also some touristic but check ratings on tripadvisor before choosing).
The apartment was very clean and the terrace was nice for breakfasts in the open (indoor kitchen table is quite small). Communication was very fast and precise and quick support on taxis for the airport. Highly recommended.
