Good location in center of Rome, near (10 mins walk) to Roma Termini, metro and park (cross the street), few shops and bakerys, fully equipped kitchen, big, comfortable beds, effective aircondition, clean bathroom and much, much more - it's perfect place to stay for week and longer, even with kids. Great, helpfull contact with Sarah, easy way to check-in and -out.
On the map there is a tram line near the door, but don't worry, double windows cut almost every sound from the street at night. :)
