There is a little boutique hotel that sits across Circular Quay from the ships moorage, the Sir Stamford at Circular Quay. That looks really nice and is very convenient and $250 AUD using their 2+ day rate including breakfast. I expect the one night rate is higher. One recurring comment about the hotel was that the rooms are large. its only 200M from the Opera House and looks over the Botanical Garden. We looked at it but it turns out we are not going on Sydney-Beijing
