Me and 3 friends plan to visit plan Beijing from Dec 27nd - Jan 05th. We´re looking for a 4 to 5star downtown hotel that´s affordable (about 80-90$ per room/night). Could anybody give any advice?

On our list are by now the Presidential Palace, the Crown Plaza and the Gloria as well as the Prime hotel. We plan a 9 day sightseeing/shopping trip.

Thanks in advance!
