We stayed at Kate’s for the last 3 nights of our month long trip. It was super comfortable to rest in and watch some Netflix after so many eventful days travelling. It has a full kitchen fantastic for cooking.
As others have said the location is perfect to experience Sydney from, so many options to commute, ferry, train, bus or cab, super quick.
One thing in walking distance I’d recommend to future guests is Wendy’s secret garden, take at least an hour to experience it.
