Gyeongdong Market

Clean room, excellent water pressure, friendly and helpful staff who answered my questions via app, location is near Myeongdong. However we returned to one particular Korean BBQ restaurant a few minutes walk from the hotel. Laundry in the basement gave clear instructions on how to operate macines and how to pay.

Centrally located within Seoul in Myeongdong, but just outside (essentially one block removed) of all the action so it is much more quieter and a significant positive for me. Staff was extremely friendly and the breakfast buffet was outstanding. Highly recommend having the buffet at least once on your visit. Hotel is conveniently located next to the subway so it is extremely easy and accessible to get around every major neighborhood. It is also walking distance to Seoul Station, but I would recommend taking a cab/taxi/Uber for convenience as the area is generally within a major node for traffic.
