Stayed on the Club Floor, which includes access to their fabulous Club Lounge, with great views over Darling Harbour. I would recommend this option, as lounge access includes free Internet and printing, complimentary refreshments, continental breakfast, and some very classy pre-dinner snacks. Easy stroll to Darling Harbour too.
Enjoyed the stay there. The staff were friendly and the room was very nice. Expected a little bit more of the room for a five star hotel. Location was very central.
One of my favourite hotels in sydney, the hotel itself is right behind the IMAX on its own cul de sac, making it quiet and relaxing, while at the same time having a fantastic location. Great breakfasts in the atrium area (full buffet, fabulous) and a helpful courteous staff. Just the one thing: don't expect views! At best you can get 'glimpses' of the harbour, but nothing more.
