For my first time using Airbnb, I don't think I could have picked a better apartment.
The location is perfect: around the corner from Campo de Fiori; within 10mins walk of the Trevi Fountain, Pantheon and Trastevere; and the Roman Forum, Colosseum, Spanish Steps and Vatican only a short distance more. We felt very safe the entire time.
The apartment itself is huge with a very spacious living room. The street can be loud with music but once the shutters over the windows are closed, it is very quiet so the sound does not disturb sleep. There is heating/air-con so the temperature was always just right.
Carlo was our host and took fantastic care of us. He was very welcoming and had great suggestions for places to eat. Carlo even went out of his way to look after our luggage after we checked out because we had a late flight home.
I would recommend PettinariRoma to anybody interested in visiting Rome.
