Watched a video on YouTube how to get from Barcelona airport to the city center using Aerobus.
Note: no one/not the driver will place your luggage to the rack. If space is tight, you will have to move other people’s luggage who may have left it flat instead of sideways to create more space.
Cost 5.8 euro one way. Bus is cleaned and air conditioned. We used the taxi to get us to our hotel.
