There are daily, 48h or 72h tickets for take all the public transportation, also the train near home. There are restaurants near home for have dinner, so if you wanted to have dinner out my house, you could go out without problems, but it's not nice write a negative review only because you don't know.. we pick up guests only for come them at home sooner, because if you want you can walk from the station to my house or take a little bus. If you didn't want anything of your stay, you can tell this before, or choose another host. There aren't any suburbs, with the train near home you can stay in the center of Rome in almost 20/25 minutes. I write about you like a nice guys, because this is the feeling that my family had about you, I'm only so sorry for haven't read this before, bye.
