Stayed at the JW hotel on business recently and was disappointed. I also stayed at the Courtyard Pudong/Shanghai. The Courtyard was much better for business. The only thing I liked about the JW was the view - it was spectaular. I found the JW was hard to communicate in checking in using English/Courtyard was excellent. The bar on the 38 or 30th floor had service that did not understand the term - they thought the fastest you ordered the better and were unprofessional in service - tried to relax on a Saturday but kept asking literally every 15 seconds what I needed - why don't you order - why do you not want to order - want another drink - and I am not kidding about every 15 seconds. I left and went to the Ritz Carlton and had a wonderful evening there - I would not suggest to stay at the JW - not worth it. The Courtyard was excellent - does not have the view but the service was outstanding, especially the executive lounge and front desk. I have stayed in JW's and was always pleased but the Shanghai JW is not worth the price and not up to Marriott great standards. I would recommend the Ritz Carlton which I also stayed in recently and was excellent in every way.
I tend to agree.
I recently stayed at the Shanghai JW Marriott and would say the price premium is difficult to justify except for i) the location and ii) the gym - which is pretty good.
I found the Concierge lounge service was very poor. Lots of staff, but none of them seemed to be interested in helping. Just a lot of standing about. Also, I was expecting a much better selection of food than they had. I preferred the Concierge lounge in the Yuyuan Renaissance.
Breakfast selection in the cafe was OK - but I think it was better last time I was at the Yuyuan Renaissance.
Bottomline - if you dont need the weight machines in the gym, I would recommend paying much less and staying at the Renaissance.
