Mario's place is close to a metro station which is about 6 stops away from Roma Termini from where you can easily reach major attractions by metro. Their place is homely & friendly and the room we stayed in was well decorated & maintained. Mario & his wife took care of our vegetarian preferences, which is very nice of them. They both are caring hosts. We will definitely recommend their place to anyone. Thank you Mario & family (they have a cute little baby girl now).
