Where to start?
If you look for a affordable room close to the centre, here is the perfect one. It's in the real Rome, far away from all the tourists but everything is easy to reach with public transport. And there are good and cheap restaurants close by.
But the real treasure of this room is the just Federica. She speaks perfect english and gives you all the information you need. When we took a little longer to reach the place, she already got worried and wrote us a SMS :). She is really lovely and helps wherever she can. Same as her friend or boyfriend (never found that out :) but he only speaks Spanish and Italian. But he really tries to help you too.
Long story short... If you look for a place to stay, there is no better choice than this place (sadly it is already booked for our next stay in rome)!
