Mattia is a savious, he accepted my request at a very last minutes. I had a nice and good experience staying in Mattia's place. He himself a charming, friendly, helpful and nice in person and also always attentive to his guest. We had nice conversations during my stay there. As for the place, it is about 15-20mins from Central Rome by train. The place is located in an quiet neighbourhood, so you won't hear much of the traffic except for birds chirping. The room is huge and functional, love it to the maximun. You have access to the common areas; kitchen and living room and toilet is super clean. Mattia's place is totally recommended. I would come back for sure. Thanks Mattia :)
