Casco Viejo (also known as Zazpi Kaleak) is both a metro station and a commuter rail station for EuskoTren. I was here to exit the metro, which was easy and well marked. Clean station, well lit and no smell of pee which is usually expected in metropolitan subway stations.
It is in Zone A of the metro and on Line 1 between Abando and Santutxu stations. There are automated ticket vending machines, turnstiles and overhead displays that announce the next train. Signage is in English and in Spanish. read more
