Having stayed at the J.W. Marriott in downtown Seoul, I find this to be one of the very best hotels I've ever encountered, and I travel all around the world. The facilities are impeccable, the service unbelievably good, and the breakfast buffet is unparalleled. It's such an easy hotel in which to function, the rooms are comfortable and inviting, and there is plenty of space in which to meet on either a casual or formal basis. I've always found it conducive to doing business, and due to its central location, it's easy to get customers in Seoul to come to you--so you don't have to deal with that incredibly awful traffic!!
