At the first night, the door was broken and cannot be opened. We have to go to reception for 3 times for requesting a help. When we successfully went inside, still the door was broken again and we completely locked out of the room for around 1 hour. When we insist to transferred into another room for security reason, they declined and said all rooms have same door problems. Their receptionist was impolite, and not really helpful. Location isn't that great, far from the city center, and you have to walk and cross the street 3 times to go to MRT station. Never going back when we travel again to Seoul.
