Paola and Andrea were lovely and made our stay very pleasant. Andrea made sure we knew how to reach the apartment from the train station, and he was there to welcome us and show us around.
He was very accomodating when we asked if we could have two sets of keys instead of one. Paola made sure we had an internet connection and brought us extra sheets for the futon the first evening. The apartment is as described, very neat. The loft bed upstairs is so comfortable!! (bonus points: cutest toilet and bidet set I have ever seen...)
Check-out was very easy, they were very accomodating with a later check-out time, so we were able to leave our luggage there while we shopped in the neighborhood. Andrea also was instrumental in us not missing our train!! He called us to alert that the subway had suddenly closed, and he was able to find us a taxi (he literally stopped the cab driver in the street and asked him to wait for us... amazing) It was a great airbnb experience.

They also left a very nice book in the apartment for us to browse. It lists all the fun/funky stores in Rome, organized by neighborhood. I discovered that "the" place for Marrons Glaces in Rome (Giuliani) is very close to the apartment, and I also visited a couple of interesting clothing stores thanks to their recommendations.
I liked the Ottaviano area (Prati neighborhood), I did not know it very well beforehand, but it was very easy to navigate, and walking to the "touristy" part of Rome (Piazza Navona etc.) was easy and beautiful. Thanks so much Paola and Andrea
