Roberto was a wonderful host! He met us at the door of the apartment the day we arrived, and oriented us to the building and surrounding neighborhood. The apartment was just as described: small, but well equipped, and perfect for the two of us (my daughter and me). The neighborhood is navigable and has quite a few places to shop if you're looking to get gifts for friends and relatives. There is great coffee, gelato, and pastries everywhere.
We arrived rather late on a Sunday, jet-lagged and hungry. Roberto called the restaurant at which he'd just eaten and asked them to stay open for us. They did, and we were so grateful because the food was incredible. O' Cuppitiello is the name, and it's run by a husband and wife who are very hospitable. Roberto gave us a list of other places to see in the area that were easily accessible by bus, metro, funicolare, or walking. We had a wonderful time and would highly recommend!
