First of all, Sergio was a great host. He explained us all the stuff necesary to arrive at his home (including the bus tickets price and the easiest way) and he waited for us as we arrived in the night, at 2:00. He listened to all our needs and told us suggestions like where to eat, what bus/metro should we take etc. The room looks exactly like in pictures. The area is close to metro and bus stations and 20-30 minutes of walk from Colloseum.
