Tania and Flaviano are great hosts. They have been really flexible and waited for us late at night. The apartment was as described and clean. We enjoyed our stay there a lot.
It's a bit far from the city centre (Termini train station) about 35-45 min depending on traffic, but the bus stop (bus line n°38) is very close to the appartment and goes directly to the train station which is super convenient.
Highly recommended!
