CTS hotel is a 'famous' hotel operated by China Travel Service Group (CTSHongkong is totally different one which operates Metro Park Hotels in Hongkong and China). Although CTS hotel's lobby looks upscale, its room is awful!!! Everything in room is outdated and faded, metal stuff are rusted, furnitures are old, sheet is not considered clean if according to its four stars rating and price. Lots of western guests stay in CTS hotel mainly because they join tour operated by CTS. Hotel location is considered good, 10 mins walk to subway station which is the closest station to airport on airport express line and interchange station. If people are planning to stay in the area, Novotel and Ibis are much better (newer and right next to subway entrance).
