We are going to be in Shanghai for 4 days late Nov. It looks like the Renaissance Yu Garden Shanghai hotel looks to be in a good location to Metro and seeing sites. Is this a tacky area? Or a good place for a base to sight see? We want a place we can walk out of our hotel and find good food and things to do at night within walking distance. Our other choice is in the French Concession area or Xintiandi area. We are willing to spend up to $300 USD per night. We will also try to go to Hangzhou for a day trip. Any thoughts appreciated.
