Have stayed here many times now. This is my choice whenever staying in Beijing. Summit Wing is in tower 3 (not to be confused with the much older China World Hotel in tower 1). The hotel is new (less than 1 year since it opened?). Staff are fantastic. The rooms are terrific, good size and with modern Chinese/English fusion decor. There is a brilliant spa, gym and pool in the building and the hotel links with the massive China World complex with cinemas, ice rink, shops etc. You could make the mistake of just staying in the China World complex it is so vast. I rate this hotel as one of the best that I have stayed in anywhere. It leaves the standards in Australian and many Hong Kong hotels for dead. Im not sure what constructive "criticism" I would make of this hotel. It is just so polished in almost every way (with about the most comfortable bed you could have).
