"This stay was in their Ambassador Suite. It was on the 41st floor, so near the top, but even from there one can barely glimpse the harbor through all the new construction in Sydney CBD. Still, it was a nice room that included executuve lounge access as well as breakfast at the Glass restaurant.
The Executive Lounge used to be located on an upper floor, but they've relocated it to an enclosed area (no windows) on the 1st floor. Usable, but the space is smaller, the food offerings are less than before, and there is no view so the aesthetics were not as nice. But at least it's open 7 days a week with decent hours. I do recommend the Glass restaurant for breakfast any day, if you have that option.
The room itself was divided into 3 parts, a bedroom, a combined dining/living room area, and a connecting large bathroom and walk-in wardrobe area. I picked this larger room because I had my daughter and her 3 children with us on this trip. My wife and I chose a "City Suite" for ourselves that was more suited to our needs.
Their standard rooms are nice, but relatively small. Service was excellent throughout out stay.
The main reason we picked the Sydney Hilton was because of it's location next to the QVB as well as the convenience of having light rail (street car) and rail access nearby. You can actually catch a train from the International (or domestic) airport and end up at the station next to this Hilton (Town Hall) without changing trains. But this hotel is very nice as well."
