2 years ago I went to Beijing for work and stayed at the JW.
Great hotel. As a platinum, I got to eat in the restaurant for breakfast and it was great.
Location was awesome too!!
I took the taxi to go to/from work (worked near the Olympic Water cube)
After work (and on weekends) I went to the mall across the street for meals, and took the subway to go site seeing (only 2 blocks away).

Now, I will be going back to Beijing, but for some reason the JW is only available (with our corporate rate) on the weekends this time. (October)

Which do you recommend that has these qualities:
1. Good executive lounge for elite members
2. Good breakfast (free for elite members) in the restaurant
3. easy walk to the subway (I loved going to the silk market)
4. near a mall (so I can get dinner)
5. comparable taxi ride to Water Cube

These are the hotels I am thinking of: (too bad Hyatts are too expensive)
Renaisance Beijing Capital
Marriott Beijing City Wall
Renaissance Beijing CHAOYANG
Doubletree by Hilton Beijing
Hilton Beijing (not Wangfujing, that is not available with our rate)

Thanks!
