What a great hotel with world class service. From the moment we checked in, most of the staff addressed us by name. They were so helpful during our first visit to Seoul. Even the GM of the hotel helped us with a sightseeing itinerary, and restaurant recommendations. Located right on the Samseong subway station, with underground access to the Coex mall, and convention centre. The hotel provided us with free subway cards and a free shuttle to the City Airport Centre where you can check in for your flight before heading to the airport. The room was spacious and high tech, including a heated self cleansing/drying toilet seat.

First, I must say that the Park Hyatt is quite a good property with spectacular desk service and no glaring deficiencies, yet I found it a bit short on several counts relative to other properties that have earned such high marks on the Conde Nast Gold List, which joins TripAdvisor as a highly trusted source in choosing hotel stays.

Likes:
Warm and intuitive desk service
Airy rooms that maximize natural light
Generous amenities and daily fruit service
Aesop toiletries
Complimentary business center
Excellent culinary team and in-hotel dining options
Museum-like exhibit cases in corridors

Disappointments:
Too much street noise in room due to expansive use of glass
Room maintenance standards lacking with scratched floors and torn upholstery seams
Visibly dusty hallways
Attentiveness of restaurant staff was hit or miss
Less than ideal location for a leisure traveler

To the hotel's credit, they were very responsive to my room concerns and they noted that a room renovation program is beginning. Having found the rooms just slightly tired, I would for now return to the Westin Chosun due to its better location for leisure, better sleep quality, and typical price differential, especially since common areas at the Chosun were recently updated. That said, a class-leading room update could draw me back to the Park Hyatt and I am certain their efforts will be excellent and inviting.

I arrived early and was told (very graciously) that although the room wasn't ready, I was welcome to enjoy complimentary tea in the sitting room. It was delicious! That was only the start to a fantastic stay. The room was elegant. The staff was friendly and professional. A wonderful hotel in a great location!

It's the subtle touches that separate the good hotels from the great. The Park Hyatt understands this well, and goes the extra mile to ensure guests feel welcome and well taken care of. While I'm tempted to explain in detail, I won't ... as part of the delight comes from being surprised by the small details that this hotel goes considerable lengths to provide.
Side note: get a room in as high a floor as possible. I was on a lower floor which at times was a bit noisy due to the highway traffic immediately outside.
