I often choose Hyatt Centric Zhongshan Park when I'm traveling to Shanghai for business due to its unique and convenient position (5 minutes walking distance from Subway N.2 and close to Yuyuan road with plenty of restaurants and bars).
My room was as usual clean and impeccable.
If you stay there, you must not miss the breakfast at the second floor which is really tasty and superb!
I would like also to praise Lilian, one of the front desk staff since I'm really impressed for her willing to help attitude and kindness.
