Futuristic Setting from the outside and beautiful setting on the inside.
Lovely rooms with beautiful view at times. Comfortable bed and pillows.
Connected to a mall, train station via the basement and lots of Eateries and convenient stores.
If you are checking in late, there's a McDs in the mall's basement and lots of other Local Korean Eateries across the road.
Huge Supermarket called Home plus, across the road. There's an underpass from the hotel entrance lobby, that connects the walkways.

The elevators are tricky. You have to take 1set of elevators up to the Guest Check in Lobby and then take a different set of elevators that will get you to your rooms.
The elevators that bring you to the hotel entrance lobby also brings you to the Mall and Eateries in the basement.
(Hope that wasn't confusing. Ask the staff for help. They spoke English well.)
Side note - People do cut in and get to the elevators that bring you to the lobby level, if you don't move closer to the elevator doors. If you are going to be too polite, you will wait for a long time, while others cut in and get into the elevators. Don't be shy!
