My experience this April is pretty much what SanDiego1k said.
I am a Coke Light drinker. Lounge only stock Pepsi products but I found Coke Light in the room's mini bar. I inquired with the waitress in the lounge and she told me Pepsi is all they have. No problem, I am used to carry my own diet Coke staying in Hyatt properties. When I go there for the evening cocktail, she told me they will stock Coke Light in the back room for me.
Excellent service and a great location to unwind. We were working in Shanghai and I took the D train back here to spend the weekend. There are two train stations in Hangzhou, make sure you check which one is closer to the hotel. Hotel was sold out, but I was still able to get a lake view room. This is a very popular destination for Chinese. Going to West Lake for them is like going to Grand Canyon here. I am looking for excuses to get back there later this month.
