. Advised two others to use and were thrilled about it. Buy ticket at train station or on board for a small surcharge.Cost is US$16 per day on-off unlimited or US$10 for staying on bus for 1-1/2 hour sightsee ride around Rome. Pay in cash or creditcard, cashier speaks English at termini kisok; guide on board to advise which way to sight you want to see (must ask). After orientation, you'll go back day after day.Bus is only tourists unlike public trans, pickpockets galore.DO NOT CARRY PURSE,KEEP BACK POCKETS EMPTY AND SAFETY PIN FRONT POCKETS WITH WALLET; USE MONEY BELT NEXT TO SKIN AS TIGHT AS POSSIBLE AND PINNED. THIEVES TRIED BUT GOT NOTHING FROM ME.
