You're going to love staying at this apartment. It is really well located, you're close to Vatican city and Saint Angelos Castle. There are several bus stops around that take you to the most important places in Rome within 30 minutes.
The apartment was sparkling clean and the hosts were very clear as for what they expected from us and what could we do in the building. They suggested tons of places to try pizza and other Italian delicacies.
They are really responsive, really, anything you want, you will get a response. I think this has been, by far, the most professional Airbnb experience I've ever had.
