Mario's home is situated in a neighborhood away from the hustle and bustle of the tourist areas yet, it is just a few meters away from the metro that will take you there. He gives you full reign of the house so you feel like the host and he is the guest. His place is clean and cozy with interesting books, furniture, and Mario's artwork.
Mario is a kind and generous host, an artist, and gentleman. I would highly recommend his place to anyone who was looking for a place to stay in Rome.
