Very nice and clean apartment, perfect location - no too much tourists around, but the touristic area is easy to reach (15 minutes) thanks to the couple of buses in 2-5 minute walking distance.
Small shops, very nice local restaurants (we tried 3 around) are just at the corner.
Ciampino airport is 1-1.20 hours distance, but we managed to reach our plane in time which left at 8.30AM!! :)
We haven't met Christina or Franco (some of their friends helped us to settle down) but they helped us by e-mail almost immediately when we had questions.
I can only recommend this place/them!
