Considering the Residence Candia in Rome?

Ticket Settimanale - The first thing as you arrive by Frisbeeace
As soon as you arrive in Rome, go to a Tabacceria (kind of drugstores with a big T on the door) and buy a metrobus ticket settimanale (7 days) for E 12.50 each. Then you can board all buses and metros without limit. Nobody won't ask you ever for the ticket but you may be fined heavily if it happens. As you board your first bus you have to validate the ticket inserting it in the machine on board. Same at any metro station.
