This was probably one of the best hotels I've stayed in based on room amenities, service, attitude of employees, dining options nearby, ease of access to the most popular metro lines, and convenience store options.
I've stayed in many hotels with this being the cheapest but the most impressive. The employees are generally very nice and helpful, especially the housekeeping ladies.
You get to wash and dry your clothes in the room, cook in the room (I didn't do this), have acess to a microwave, have a full sized fridge and freezer, and have an air purifier in the room. These are all extras ontop of what a standard hotel would generally provide in the room.
Hotel is very nice for a long stay. I used to stay near Myeongdong/Euljiro-1 station but this is a good option.
