Pass for metro/bus/tram by ATLC
For ? 16 you can buy a public transportation pass, valid for 7 days, from the first validation. We made excellent use of it, the metro is easy (essentially just two lines). The busses were a bit more difficult but the easy part was that the end station (Roma Termini) was only 100 metres from our hotel.More information on the link below (in English). You have to scroll down to where you see 'CIS Weekly Ticket).
The pass itself is called CIS (Carta Integrata Settimanale).
