I'm heading to Sydney the last 2 weeks of August with my wife and 2 teenagers. Since we would prefer to all stay in 1 unit, I came across both the above choices since they both seem to have 2 bedroom suites and both with good locations and good views.
My sense of it is that the Quay Grand is more upscale and more expensive while the Quay West is better value and may have better Harbour views.
Would any knowledgeable reader care to comment and advise? Thanks in advance.
