Great crash pad between a regional Aus flight and international flight. Very tidy and peaceful. Everything needed for night. Right off the green line train (the circle from the airport to Circular Quay). The neighborhood is residential but it was super easy to get to the CBD. In the morning we took an Uber to avoid paying two Opal airport access fees.
I would not be able to stay more than a night because the mattress was too firm for me, but great option for a layover.
