The apartment was great, it looked like in the photos. We felt a little bit like in a hotel because Angie, who is very nice btw, took care of all the little details that make your stay comfortable. For example, she prepared a few things for breakfast for the next day for us, because we arrived late at night. Bathroom and kitchen were well equiped. Everything was clean. She recommended a few local restaurants to us, which were excellent (go to the pasta place!)
To Vatican it is a 15 min walk. Highly recommended!
