Cristina is very friendly person. She helped us with check-in a lot !
More, she kindly showed us good places to eat and visit.
The appartment is nice, the accomodations are very convinient.
The location is near to the trastevere station (10 min walking). And the bus 170 take you to Piazza Navona in a bout 20 minutes.

The only negative is the noise. Indeed, the persons who were in the appartment next to us where very loudy. Not because they speak very loud, but because the only separation between the two apparments is a simple door (directly in the bedroom).

Exept for that, I would recommend staying in this appartment for a short visit of Roma.
