The worst hotel I have ever stayed at in my life, however we stayed there to go to everland and it was very near to it, but there is absolutely nothing to do there at the hotel or around it.
No room service, no concierge, no one to help you with luggage, staff do not speak English well enough, they try to be helpful but with the language barrier and almost no knowledge of anything outside the hotel their help was useless.
Room is okay but I would never stay there again and I would recommend staying at one of the hotels in the bigger towns close by, or staying at Seoul and making a day trip to everland as it is not that far.
