I've stayed at this hotel 3 times now and each visit has gradually improved.
I attended a meeting here, if I was sight seeing it wouldn't be my first choice. The hotel has all of the usual features you'd expect from a good Renaissance- rooms were good sized, well kitted out with ipod dock, Molton Brown products. I stayed in a room on the club level which I would recommend as the club lounge is great for breakfast or a light snack, drink later in the day.
Main highlights - club lounge, good sized indoor pool and hot tub, spa, Raymond and Jimmy the concierges are good guys.
Main lowlights - noise carries between the rooms. If TV noise from the adjacent room bothers you, bring earplugs. Also, I struggled to make myself understood with some of the restaurant bar staff. Rather shamefully I can't speak mandarin so had to resort to slow English with some enthusiastic finger pointing - but even that failed dismally to order 'egg fried rice' from the bar menu. Got a bit frustrating after a while as my expectation was that at this class of hotel, English would be fluent. However, I reminded myself that I was in China and I should be trying to speak the local language.
