It was our first experience with Airbnb and it was a great one!
Marcella was really nice and took care of us. She gave us a lot of advices before, to prepare our coming and during, like good restaurants. She also had a very nice attention for my girlfriend's birthday ;).
The appartement is brand new (all restored) and really well located (2min30 from the Piazza Navona!). So it is clean, functional and very cosy.
The neighbourhood is very nice and so central that you can visit Rome by feet, without using the public transportation. Just one point to consider, there is a bar on the square, so quiet visited :). But that is also what we come to find when we go to Italie and Rome: the italian way of life :).
In conclusion, we had a great stay and we deeply recommend this appartement!
