Hi, I'm having a long layover in Bilbao (14h) from 19h/8pm until my next flight at 9 the next morning, I've seen that the airport closes at night but that the car rental lobby was still accessible to sleep in, how true is that? And what other cheap option could I have, I'm kind of scared to miss my flight if I go in the city during my layover. Thanks a lot if you can help!
