I am travelling with my-family of four in April .We are staying in Via Riccardo Moretti Cassia house.How far is it from main attractions? What is the best way to commute from our residence to main attractions?Which pass we need to buy to save money? Omnia pass with Roma pass or only Roma pass? considering that Omnia Pass is 95 €.Is the travel card included in Omnia Pass useful? we are staying 6 days in Rome?
