Sangsu Station is a Seoul Subway Line 6 station in Sangsu-dong, Mapo-gu, Seoul, close to the back gate of Hongik University and the Hongdae area. It connects to a neighbourhood where restaurants and cafes around Hongdae continue one after another, and it is convenient for reaching Hongik University. The platforms are island platforms, and the station name comes from Sangsu-dong. The exits are clustered on one side, which makes moving through the station inconvenient.
