Stayed here for 3 nights in August 2012 inbetween business and did some sightseeing. We used hotel transfer from the airport and was greeted by an immaculately dressed chaffeur complete with hat and well presented sign.
The hotel lobby is located on a very high floor which makes for great views both from the public areas and rooms. The room was well laid out, very comfortable bed and bedding, well sized walk-in shower and a Japanese bath (square tub) which I personally do not care for. Plenty of counter space, lots of closet space and great views over the CBD area.
We made use of the Concierge in arranging a tour to the Great Wall of China which turned out to be a fantastic day of exploration.
Ate one evening in the China Grill, a highly acclaimed Beijing restaurant, which served superb cuisine.
Overall this is a great city location, a high quality Hyatt property and all the staff we encountered were very efficient, polite and friendly.
