BUS
The bus network is very extensive and will cover most of your needs. Tickets are not sold on buses. In rare occasions, you'll find a machine at some bus stops. A better solution is to buy tickets at tobacco stores, cafès, and newspaper stands. Even so, non everyone sells them, so you might want to ask around. The city bus company is ATAC and most of the main buses terminate at the bus station outside Stazione Termini (where you can get a map of the bus routes). For 1 euro you can travel for 75 minutes with any mean of transportation.
There are hundreds of bus lines, running from 5:30am until midnight . All buses run in both directions.
