This is an outstanding example of the Shangri-La brand at its best. The rooms are sumptuous, the service borders on the doting, and the facilities are first-rate. I especially appreciated the fine gym, particularly in light of the abysmal Guangzhou air quality. Frankly, it's usually a requirement to exercise indoors.
I stayed at the hotel for the purposes of a conference, and I found the conference hosting facilities to be outstanding. In particular, the catering of lunches and the conference banquet was appropriate and borderline decadent.
However, prospective guests of the hotel should be aware that it is located near the trade fair facilities - and the trade fair facilities are located far from the center of town, away from most businesses and tour attractions. So, if you're going for a conference or trade fair, the location should be fine. But for other purposes, you may want to try a different location.
Likewise, the price is quite high by Guangzhou standards. However, it's a Shangri-La, and the location is outstanding for anyone seeking a luxury room in close proximity to the trade fair. So plan accordingly.
