Which is better, Hangzhou Wang Hu Hotel, Renhe Hotel (by the West Lake), Kyle Polo Holiday Hotel or Huachen International Hotel?

It depends on what you personally want.

For example, Wanghu Lake is the closest to the West Lake, which is basically the edge of the West Lake. You can see the West Lake clearly from the tall building. The restaurant on the roof of more than ten floors and the barbecue on the terrace are very emotional. It is also an old hotel.

Renhe is old, but perhaps the conditions are not as good as looking at the lake.

Kelpolo is about 15 minutes away from the West Lake, not by the lake. But it is also the most central area in Hangzhou, belonging to the general hotel that opened in recent years.
