I am staying at the Westin Sydney at the moment for the fourth time this year (32 nights so far this year at the place) and have to sing its praises. This time around I am in the Historic wing for the first time after spending all of my previous visits up in the executive floors of the tower part of the hotel. (floors 28-31)
I believe that given the choice, I would stay again in an executive floor of the new tower due to the nice views, but am actually enjoying my stay in the historic part of the hotel (high ceilings, plenty of room, lack of view though). Either way you get access to the executive lounge if you are platinum.
Right in the heart of downtown, only 5+ block walk to Circle Quay, two block walk to Wynard subway station. Lots of nice restaurants within walking distance. Very centrally located. Suberbly friendly staff. Good hotel gym (free to platinums)
Two thumbs up!
