By plane A train runs between the Airport and Plaça de Catalunya. Hostal Oliva is just three blocks from there. A very useful Aerobus service also runs between the airport terminals and Plaça de Catalunya, where the trip ends. You can either walk from there or wait for a few minutes in Plaça de Catalunya until the bus starts its way again: the first stop is then right in front of Hostal Oliva.
