Giancarlo's place was fantastic. He met us on arrival and gave us loads of information about the local area.
Apartment was great, everything you would need, comfortable and great location. Can walk into the center of Rome (about 45 minutes) and on the doorstep of Vatican city. Round the corner is a 24 hour supermarket and there is a great patisserie across the road.
Check out was very easy and Giancarlo even booked us a taxi. I would highly recommend this air b and b.
