I've stayed at the Wyndham in November 2012 for business and enjoyed my stay. There is no hotel of this quality in Pudong that can compete for the pricing.
i found the staff very helpful and the General Manager very present and dedicated. The Chinese restaurant on the 2nd floor is absolutely delicious.
Make sure you always carry a Chinese card of the hotel on you at all time (even coming out of airport) as the taxis are not all aware of this hotel. It's not in the financial disctrict although not very far.
I would understand the complaints about the surroundings of the hotel as there is not very much to do or visit. However, taxis are so cheap and available that it's quite convenient to move around town from there.
Concierge was very good and recommended us a great restaurant on the Bund. So great, I went there twice in the same week. Taxi ride from Wyndham to the Bund will take about 30 mins with traffic and will cost around $10US.
Great location if you are in Shanghai for a tradeshow.
I'm planning to go back there in May 2013
