We stayed for 4 nights in early October and had a very nice stay. The hotel is clean and well laid out and the rooms very nice. We payed extra to be upgraded to a better room and get executive lounge access and it was well worth the extra money (roughly USD$100 per night), even if the lounge was a bit crowded most evenings.
The only negative of our stay was dinner one night at Hawka, one of the hotel restaurants. After a few challenging days of dining at local restaurants (most of which were very good once the ordering was taken care of), we were tired and looking for an "easy" dinner one night with our children. Although the hotel restaurants had five star prices, we figured it would be worth it one night to get the five star service and not have to deal with the language/cultural challenges of a restaurant outside of the hotel.
The food was good, and the service was ok, if not a little too intrusive/over attentive. However, part way through dinner my husband accidentally knocked over a beer, and the glass it was in broke. After doing a quick and not very thorough clean up of the glass and beer on the table, the staff seemed to start avoiding us for the rest of the dinner. That was fine, until at the end of the evening the manager, "Andy" came by and started discussing compensation. We initially thought that he was comp-ing us for the beer since it was mostly full when it was knocked over, but eventually we realized that he was charging us for the glass. Not what we expect in a restaurant in a five star hotel, but we said ok. When the bill came, they had charged us 150 yuan (roughly USD$25) for a standard beer glass (about five times the cost of a TsingTao). We called Andy over and questioned the excessive charge, and he just grinned and said that was the cost of the glass.
We'd stay at the hotel again, but definitely not eat at Hawka. We would have given the hotel 5 stars, but knocked one off for the restaurant experience.
