I enjoyed my stay in Mario's place. The location was very nice however, it is not near to the Vatican. It was a 40 minute bus ride, a 20 minute taxi ride or 1 hour 20 minute walk to the Vatican. There is a lovely little cafe just on around the corner which serves excellent espresso and pastries and a supermarket around the corner in the opposite direction which provided me the ability t cook my own meals. The apartment was very clean and the air conditioner worked well, I would stay here again now that I am familiar with the location and would use the bus to travel into Rome to save money on taxi fare.
