I have just spent 5 nights in the Four Seasons Sydney. I have stayed on other occasions. Its position is excellent for the Harbour and always come back. The facilities are very good. The rooms extremely comfortable if slightly smaller than some comparable hotels. But the thing that is absolutely stand-out about the hotel is the staff. They are the best trained hotel staff I have ever come across - and I stay at a lot of 5* hotels around the world. They are unfailingly friendly, responsive and incredibly helpful. Gym open 24 hours and very good facilities. Also for the record, I went to the Handa Opera on the Harbour performance of La Traviata. It was absoutely fantastic. Unmissable event.
