The Hilton hotel in Chongqing is a bit old, but beside that it is a super hotel, with fine rooms and a good service. Specially the guy with the english name Leonard were very helpfull and service minded. Nice breakfast but the best part were the executive lounge, which we can only recommend.
If we should mention something they could do, is it some renovation and also teach employees to be better in English. But all in all a pleasant stay.
