Brand new building - VERY CLEAN rooms (except shower floor could've been scrubbed better). Comfy beds.
No check in staff - you get a text with your room number and door code. Luggage storage on 2nd floor (with door code).
Major minus: you have to communicate with a chat service 9:30a-7p only. They're a bit slow sometimes and they always change their answers. Example: in the room it says "ask the day before about late check out, 10,000W per hour." So I asked the day before. They said "ask the morning of check out." Ok........ So I asked on check out morning and IMMEDIATELY they said "no sorry the cleaners are busy and need the full time" (I asked for ONE hour). It was odd because the building wasn't full at all, I barely saw any people....
Absolutely will stay here again next time though. Just two minute walk to Seomyeon nightlife, exit 12 of subway station. Nothing else is this convenient or affordable!
