To drive from the airport to the city center, the easiest way is to follow all the signs that point to ‘Centre ciutat’ (city center) going through ‘La Gran Via’. It is quite well indicated so shouldn’t be a problem. Cars can be rented at the airport. Main car rental companies have desk at the airport.
To get back to the airport fom city centre, take the motorway that goes to Castelldefels (C-246) and follow the signs to the airport.
Last option is taking a taxi although price can vary from €15 to 25€ depending basically on traffic.

Tip: I would strongly recommend using the Train or the Aerobus as they quick and cheap. Taking a taxi may be expensive as traffic is getting worse and worse in Barcelona

The price for all or part of each 24-hour period is €4.50 for a large locker, €4 for a medium locker and €3 for a small locker.
