We've been in Dario's flat for one week in september. The room is comfortable and clean. There's a kitchan that you can use and Dario buys some things for the breakfast :) Dario himself is a very good host. He's nice, funny, polite and helpful. He will tell you everything you need and if he doesn't know something, he will search the internet for you. Localisation is also good. You can get to the subway station in few minutes on foot, and it takes about 15-20 minutes to get to the city centre by mentioned train, so it isn't really a problem. Moreover, it is located quite close to the Campiano Airpot. It takes about 30-40 minutes by bus and subway to get there. We can recommend Dario to everyone and if we ever gonna be in Rome again, we will choose his offer :)
