Do you know which five-star hotels in Hangzhou are better?

There are many five-star hotels in Hangzhou. I have been in Hangzhou on business for some time and stayed in several five-star hotels. During this time, I found that several hotels are particularly good, both in terms of housing configuration and service attitude. Hangzhou New Century Du Ming Hotel, Hangzhou Huanglong Hotel and Hangzhou First World Hotel.

Of course, besides these, there are other hotels that I haven't stayed in and don't know much about.
