Hi can anyone tell the name of hotels in the centre of shanghai at a reasonable price ,comfortable?

Hi, what is your budget?
Many hotels of different classes in the downtown can be found. Considering the transportation and travel convenience, I suggest you find one near the Bund.
For budget hotels, you can go and check in Super 8 Hotel, Hanting Express Hotel or Home Inn nearby.
For mid-level accommodations, Motel 168 (the Bund) is most suggested.
For better ones, XingYu Oriental Bund Hotel can be ok.
