Average - not really hilton material
Small hotel, small room, small service.
For anyone used to quality of accommodation and customer service in Asia, brace yourself. This is well below what you are used to.
Good - 
- easy check-in, check-out.
- korean restaurants nearby, if you like the food.
Bad - 
- no restaurant in the hotel, and limited bar.
- gym is so small
- no pool
- forget about late check-out (they will hammer you with fees, US$109 for 4 hrs...)
- concierge with no real expertise (only OK to give out free maps)
- in-room dining platters in the corridors all day
