Enjoying my stay, upgraded to a deluxe room (not a corner) but that's ok, on the 30th floor.
Gym is closed, breakfast buffet open but closes 10am and I didn't intend to be up so took the points. Hotel kitchens close late afternoon - no dinner in restaurant or from room service.
Room is nicely spacious and bathroom has both shower and bath, though not sure I would use both at once. Also the enema button still exists.
Oh and it now called "Four Points by Sheraton Seoul Station".
