Where can I find a map of the area where Kerry hotel is located in Shanghai.

It is difficult to understand from the big maps.so the area of about 4 KM around Kerry hotel would be great. I need to stay in a hotel which is near Kerry as a friend is staying there , but I want to stay in a cheaper hotel, which is walking distance.
Please also where is Kerry hotel situated, what is the area called.what are the places near it.
Thanks in advance.
