What is with all of the good reviews?!
This Hyatt is terrible!!!!! The carpet in the halls is ugly and stained. The rooms have paper-thin walls and they are small. The rooms have recently been renovated which makes me wonder what they were like before the renovation. They are small, out-dated,etc. The windows are FILTHY, just FILTHY.
Having recently stayed at the Hyatt in Shanghai, it was a COMPLETE letdown. 
Do not pay extra for breakfast included. I went once and once is enough. A little bit of fruit, cereal and if you order poached eggs, they are overcooked. 
The staff was friendly, this is my ONLY compliment.
Also, they don't have a swimming pool.
