Any qualms about the unhostel-like prices will be shelved the moment you head up to the ample rooftop space of this sprawling, modern hostel and see the superb views of Circular Quay. Very well run, the hostel has spacious en-suite four- and six-berth dorms and a selection of decent-value-for-Sydney private rooms. There are also numerous sustainability initiatives in place.
It's located on top of an archaeological site; you can check out the remnants of the convict-era houses downstairs. Loads of activities and tour bookings give you lots of options for your stay.
