It was our first time using Airbnb and I got a hard time to convince my parents to use it in our trip to Italy, instead of paying for a hotels.
Maria, the assistant was really helpful, kind, and was helping us in every little thing we needed to make our stay comfortable. She even brought us a nice, complete breakfast which we really enjoyed. It was situated in Campo di Fiori, so excellent location.
The only con is that the apartment has nothing to do with the pictures, my parents arrived first and didn't like it as it was not as the pictures at all (I think they have several flats and only show one). Fortunately since they are all so nice, they changed us to another newly renovated and pretty room right beside the old one. At the end our stay was pleasant, but careful to trust only on the photos.
They also made us feel like home :)
