My boyfriend and I spent 10 nights here and loved it. We booked a private room for the duration of our stay but I'm guessing it was normally a dorm/family room as it had a double bed, bunks and en-suite bathroom.
It was pretty basic, like most hostels and didn't have as many walls as we were expecting (the communal parts are very open plan!) but we enjoyed our stay here and loved being so close to King Street where there are LOADS of nice restaurants, vintage clothes shops, music stores etc.
It's 10 minutes to the city by bus, the staff were really friendly, there were plenty of leaflets about day trips and activities and there was a massive noticeboard advertising jobs and stuff going on in the local area. The free internet access certainly came in handy, too!
When we visited, the weather was rubbish and the other residents (mainly long-term) kept themselves to themselves. But I imagine the hostel is great in summer, when everyone socialises around the little pool.
We stumbled across the hostel's website online but when we got chatting to people in Sydney, they were impressed we were staying in Newtown as it's such a trendy area and most tourists miss it completely and head for the city centre.
I'd definitely recommend it to anyone.More
