We stayed here one night to celebrate our anniversary -- but took our three year old daughter with us. We had stayed once before, and enjoyed the room and pool, but on this occasion, guest services really went above and beyond. We were upgraded to a club-level room, which had been decked out in rose petals. We had a cake and a bottle of wine waiting for us (the latter wasted on us, since we don't drink) and a bouquet of flowers delivered to our door.
All in all, we were made to feel most welcome. Having stayed at this hotel even without the special attention, the rooms are nice and airy, and the location is fairly convenient for beijing (it's on the subway, although line 1 is very crowded). The pool is great, although the jacuzzi/steam room/saunas are gender segregated. The restaurants are good but pricey.
We had a very special time, thanks to the hotel staff. We will stay again.
