From Youth Hostel to Deluxe 5 star hotel, no matter what hotel you expect, most Favorable ones with lowest discount to 30%-80% are all available here. Bookings here could be processed free of charge and immediately, and you could pay at arrival!
The service is good. Room is clean as well. However, the price is a bit high especially in the exhibition period. But I don''t know why people can even get a lower price for walk-in than through the booking from ctrip.
