So , this was our first airbnb experience and I think Mr.Cristian was one of the best choices we could have possibly made. As a host, he was very helpful ,answering back very quickly to our messages and to all of our questions regarding our stay in Rome. I really liked the fact that the house was very very clean and that he had bought some drinks and snacks for us ( really appreciated that move). The apartment is very cozy and beautiful , however it has some moisture mainly because it is like a basement/ground floor situation . Finally, the apartment is very near to bus stops and the subway station is a 10-15' walk. The area is ok , I would advise you to avoid Via Tirreno and prefer Via Conca d'Oro if you're going to the subway station.
Overall , we (me and my girlfriend) are very satisfied with our stay to Cristian's apartment and would easily recommend it !
