We stayed in a deluxe room for 3 on the 10th floor with a view of the Anzac memorial, Hyde Park and St. Marys Cathedral from the small balcony. We had no problem with traffic noise. The room had a small seating area next to the kitchenette, the latter having all the necessary equipment for a week's stay (perhaps apart from a dishwasher!!). Breakfast was supplied daily to the refrigerator, comprising milk, cereal, toast (plus preserves/vegemite/peanut butter) , mixed fruit cartons, orange juice plus tea and coffee. There was sufficient storage space, albeit not enough wardrobe hangers for 3 people. The bathroom was very clean with washbasin, shower (with retractable clothes line), and toilet with soft close seat. Hotel also has a free launderette with soap powder available to buy at reception which was a real bonus. Internet access is available at a cost but we did not see that there was any wifi available.
In terms of location, it is well placed for Museum station opposite which is only two stops from Circular Quay and all the iconic sights. The hop on hop off bus stop is a short walk across the park. Coles supermarket at World Square is nearby and the 7/11 is a few doors down from the hotel entrance.
All in all we would recommend staying here and would visit again.
