COEX Convention and Exhibition Center

I have stayed there for 3 nights. The location is great, the staff was helpful. Did not have the breakfast, but during my stay there was a special discount for the breakfast price they said. Also they provided a discount voucher for one of the cosmetics store in Myeongdong shopping street. Room was just a normal size for the price, not a big or great room. The bed was clean. However the bathroom seems need a renovation and cleaning. The bathroom walls coverage (i dont know the material) especially on the corners of the wall were ripped off (most probably due to the humidity in the bathroom). And one last note, you need to bring your own toothpaste and brush, i guess its a general regulation in Korea that disposable products are not provided in the room anymore due to environmental protection regulations.
