Pros:
location (a few blocks from the Hanok Village, a convenience store and many restaurants nearby, a safe and quiet neighborhood); friendly and professional staff, good mattresses (not soft, not too firm), very clean, req for a late check-out allowed (stayed till 1 pm)
Cons:
expensive, a bit small (bedroom and bathroom) for the price paid, my Japan-used laptop did not work ("no networks found"), which also happened at other hotels in Korea, so it was likely my laptop issue, not the hotel's fault (?).
