You get what you pay for, which isn't a knock on this place. It's bare bones, but it's affordable, convenient to the local subway station (a short trip from several of Seoul's touring sites), and affordable. The front desk situation is hands-off, but the proprietor reaches out to me for check-in and came out to assist me when I couldn't find the hotel.
I tried to Google Map the location and had a hard time, so I'll leave directions herebin case they're helpful to someone in the future. Exit the station at Lotte Department store (or Exit 6), turn left. The entrance to the building is just past the animal hospital, and the hotel is on the fourth floor.
There is no elevator (or it seems to be permanently out of order), so be aware if you're traveling with heavy bags or have a disability that makes stairs difficult.
