Decent rooms, clean, but a bit dated. The breakfast buffet was standard HIE China fare. Good, but nothing special. Wi-Fi tends to fade during the day. I would not rely on it for business use. Unlimited bottled water was very helpful in the hot weather.
You may want to pay a little more for a better experience. If you have the budget, Le Meredien or the Marriott are the top rated hotels in Zhengzhou.
