Location wise is 1 min from the exit 5 of Dongdaemun station but it was hard for me to find a convenient store nearby (maybe I was the problem, I couldn’t see any). I recommend going through from exit 6 for a 4-5min walk if you have large luggages and don’t want to walk flights of stairs (there’s a lift at exit 6). Good place for affordable Korea trip. You pay for what you get for hygiene not the best but alright.
