I had friends that stayed at ACB, it's pretty rough, but it is right downtown. We stayed at Central City Backpackers, also downtown, similar quality (pretty rough, but who cares) It had a bar below (The Embargo, if I remember, which had it's own brewed beer on tap) IF you want a little different option, our second time through Auckland, we stayed at the Brown Kiwi...a much "nicer" place, it's a home-run hostel, large 2-story house, nice garden, etc. Alittle further out of town (15 minute walk to downtown center) , but only one block from a bus route that goes directly into downtown.
