I stayed here for 4 nights and this was one of the best hotels I have stayed in. From the moment I arrived and as greeted by a tophat seeing doorman to the quick and.professional front desk staff who spoke English the customer service was impeccable. The staff showed me to my room and then showed me how to work the lights, etc. The fantastic room service, fitness center and being connected to the COEX mall with a subway line all added up to a ferric stay. When I go back to Seoul, I know where I am staying - here!
