Our "date night" stay at the Sheraton Grand was just wonderful.
My last stay at this hotel was an enforced 2-week quarantine during the Covid pandemic, so staying in the same room type might have been jarring, but it wasn't. The rooms are spacious and beautifully decorated, bathrooms are all marble and luxurious, and every member of staff was friendly and helpful. The bed linens are luxurious and the bed is super comfortable.
We used the jacuzzi, pool, sauna and steam rooms - all spotlessly clean and void of other patrons.
We didn't eat at the hotel, or have a drink in the bar, but we did use the Executive Lounge which is well worth the upgrade. The Lounge food, drinks service, breakfast etc. was wide-ranging, continually refreshed, and the views are sensational.
The hotel is well located opposite Hyde Park, right next to St James station and Pitt St. mall. We ate dinner at a restaurant at Circular Quay and the walk there and back was quick and easy. There is even a bottle shop just to the left of the main entrance...just in case.
