Unfortunately we didn't get to meet Mario as he had to leave on a business trip, however this was not a problem and his partner looked after us very well! Mario's home is amazing, very beautifully decorated and the bedroom is large and spacious with a comfy bed. The location is great - very non-touristy which is a very welcome change, and only 2-3 stops from the main Roma Termini. then you will be at the apartment in about 3-5 minutes on foot. I would highly recommend Mario's place.
