It was fairly easy to find. From Anguk Station, exit 3, you'll find McDonald right away. Follow the road, a minute on your right there's another road beside the small shop and you'll find it. However, I think the reception is not there. I arrived very late around 9.30 pm, and when I rang the door, a very old couple let me in but they didn't know about my reservation. Lucky I he speak Japanese so I was able to communicate with him. He called the person in charge which is his daughter, and she come right away. The room was small but clean, the bathroom is outside but clean. She showed me how to lock my room, and gave me a set of key. I can go out and come in anytime I want but the neighborhood itself wasn't that happening that I just stay there and rest. The breakfast is Korean style and it was good.
