I have made many trips to Sydney, and have stayed in a number of premium hotels.
Sofitel Sydney has by far been the best I have used, (and actually cheaper than most of the others). Very professional, warm, and welcoming. All staff were very friendly and helpful, with a special thanks to the concierge, "Nick", who went out of his way to answer all my questions, and arrange a number of things for me.
I will definitely be staying there again on my next stay in Sydney.
