We had an excellent time in Trastevere and the apartment was well situated and easily accessible, even tough we arrived late from the airport. The owner had booked us a driver waiting for us at Fumiccino so we didn't even have to get lost in trains or queues.
All our questions were answered fast and with efficiency.
We expected something smaller and darker, judging by the pictures, so we were really glad. The terrasse is really nice, facing a calm and shady yard with trees and birds, facing (and protected from) sunrise and fresh and windy after sunset.
The situation is exactly what we wanted, in heart of Trastevere, a few steps from wonderful restaurants, shops and landmarks, churches, but hidden from the noise of the crowdy streets. It was a dream vacation for us.
Even tough there is no air conditionning (which we aren't big fans of anyway), we had really nice nights and no problem to accomodate to the roman heat.
Only thing to know, the Wifi signal can be really poor, but I am sure this will be taken care of really soon.
If you want to have a romantic stay in Rome, I would definitely recommend this place.
Thanks for all !
