This was my first experience of using Airbnb and I was nothing but impressed. From the booking process to check out, Guilio was supremely helpful and great at answering questions quickly. The directions on how to get to the apartment from Fiuminco airport (and how to avoid the non-legit taxi drivers!) were really good but during our whole stay, every taxi driver knew where Via della Gensola was. The instructions on how to get into the apartment were accurate. The apartment is ideally located in Trastevere... Right on the river and next to some really great restaurants/gelato stores (we used TripAdvisor to find the places to check out). If you've bought the Roma/Omnia three day pass (which I'd recommend), stop 10 of the Roma Christiana bus is a 5 minute walk across the bridge. The supermarket in the OVS is about a 15 minute walk away and a number of other attractions are within walking distance including St Peter's/Vatican, Pantheon, Trevi Fountain, Colosseum...
There were three of us in the apartment and it was an ideal base. There was a bed up in the loft and a sofa bed downstairs. The shower was great! And the kitchen served our breakfast needs... Some food was provided for us which was appreciated on the first day before we'd had a chance to get our own supplies. There was air con and the noise reducing windows worked a treat.
Guilio also helped us to organise a private limousine to take us back to the airport-it was so cool, the driver was friendly and picked us up from directly outside.
This is a GREAT place to stay while in Rome. Thanks for a fabulous experience.
