It can't be understated how nice it is to have a private bathroom at this price point.
The location is excellent with every manner of food vendor you can imagine all within walking distance, a bar, and a sushi restaurant downstairs.
Though be warned it can be hard to find, its on the 3rd/4th floors of a staircase from a alleyway.
The manager was also really nice and a really great character, I'll be coming here again when I'm in Korea!
