The hostel is in a good location, it's a bit of a walk to the subway station, but it's not too far and there are a lot of shops, cafes and restaurants on the way, so it's not a boring walk, and from Seomyeon station you get get to anywhere you want (this is the cross section of the two lines). Very nice and helpful English speaking staff. The hostel itself looks nice and in good condition, and the breakfast is great.
