23 years old spanish looking for an accomodation near Dongguk University

Hi mi name is Imanol and im from Spain, specifically from San Sebastian, Basque Country. The host university has offered me accommodation but is not interesting at all because the rooms are small and they must be shared, so there isnt privacy at all. Thats why im looking for a flat, room... I speak fluent spanish and fair english. Im an active guy that doesnt like staying too much time at home.
