We stayed here at the start of our trip round the south island, and we're impressed with this smallish back packers, you get 100mb free wifi per night and the staff were helpful and booked trips for us, they also offer a free shuttle to the train station for the trans scenic train which they can book for you.
The kitchen, bathrooms and lounge were all cleaned daily, there were plenty of showers to share between everywhere. Only down side was our room was next to a bathroom and there was a sign saying don't use after 1030 at night but nothing about not using it at 5am in the morning and the walls are quite thin so you can hear a lot!
The backpackers is very central and you can get the number 29 bus from the airport, victoria street where there are lots of pop up bars is also round the corner.
All in all a great find!More
