There are two properties in Sydney - Hyde Park and Circular Quay. Having stayed at both for 3 weeks each, there are differences that make them unique in their own way and both appealling. Hyde Park is the older of the two properties and less "American". Rooms have light cooking capability and location is a quick walk to downtown through Hyde Park (pictured). Rooftop pool deck is gorgeious
Circular Quay is at the tourist hub of downtown and very busy. United air crews stay there on layover and Concierge Lounge is a nightly happening. Gym and pool are top notch, but pool is not as nice as Hyde Park. Rooms are smaller than Hyde Park but more upscale and modern.
Views all over Sydney are fabulous. See pix from rooms in both hotels.
