The rocks YHA was great! Amazing location close to yummy coffee shops, the Sydney opera house, botanical gardens, and a 5 minute walk to the Sydney contemporary art museum. Easy to catch the train and ferry from here as well. Rooms had AC, lovely rooftop and I was able to extend my stay by 2 more nights. Not to mention the entire hostel was on top of old ruins and located in a beautiful historic part of Sydney. Would stay again!
