It's a pleasant guest house for young travelers. Not by the city center but if you don't mind some walking or riding the metro in, you can still easily get around the city. The metro is close by and you can hear them running at night. Very close to San Giavanni, the Steps of the Crusifiction, and La Santa Croce in Jerusalem. It about an hour by foot or 30 minutes by metro to the Vatican. The host was very helpful and accommodating, and prompt in communication.
