This is a very cool little place and in an absolutely brilliant location. you can walk to anywhere you want to in Rome, but all the main sights are within 20 minutes walking. It's not the greatest place to want to spend any time other than sleeping with it being totally underground and thus having no windows. Although it can sleep 4 people, I think it works much better for 2 people. Marco is a great guy, extremely helpful and couldn't do enough to help us in terms of recommendations etc.
