Wonderful waterfront view of Darling Harbor and all the ferries and cruise ships. The apartment is equipped with anything you need. We used the washer/dryer several times and all the baths were fully furnished with toiletries.
I would mention the balcony faces due West and can get warm in the afternoons. It didn't bother us as we had cloud cover most of the days and the apartment has shades on all the windows.
The apartment is on the 22nd floor (fantastic views) and the elevators are fast. Totally secure with key fob to get in the main door and in the elevator to access your floor. Your fob will only allow you to get off on your floor, so very secure.
The apartment is close to everything within a 15 min walk. We took the ferry on two different occasions. They have thousands of Uber drivers which we found a lot less (like 50%) than taxis.
Don't miss the Taronga Zoo, not rated high enough in travel guides.
