Stayed here a couple of times in September and all I can say is that this is a great hotel!
The hotel is located very convenient just 2 minutes by the free Hilton shuttle from terminal 3 at PEK. The rooms are big and comfortable, the staff is very helpful and friendly and most of them know English very well. The breakfast buffet (at least in the executive lounge) is also very good.
Would definatly stay here again.
