Giampiero is literally the best host on Airbnb. So friendly, and so dedicated to making sure you have a comfortable stay. It's an experience in and of itself to meet Giampiero. He even drove us to the airport. We will definitely stop by to say hello the next time we are close to Rome!
A couple of tips - in Italy it is the law that any foreign sojourners must pay a 3.5E? fee per night they are staying there, and it is the host's responsibility to collect that and pay it. They also have to register you and thus take a picture of your passport or write the number down on a form. I checked on it and it is legitimate, so don't get nervous about that!
