Staying at the Westin was simply lovely. The hotel incorporates the old post office in quite an amazing way. I found the architecture dazzling and the room exceeded my expectations. It had fluffy robes, a great tv, and the best bathroom I have ever encountered in an Australian hotel.
I didn't interact a great deal with the staff, but on the one occasion I asked for advice, I found them friendly and helpful. The food in the hotel is predictably very expensive, but one alternative for snacks and drinks is the supermarket that is very close to the rear exit of the hotel, and down an escalator. Paying for WIFI in the hotel would be exhorbitant too, but thank heavens for smartphones.
