I book ended my tour of the South Island here. I stayed in a twin en-suite both times.
This is good hostel type accommodation. They have a variety of rooms. I did find the pics on the website to be very honest. It doesn’t look like it was built that long ago, so modern. I was a bit concerned about ‘a hostel’ in my mid 50s thinking I would be the only one amongst rampaging teenage backpackers. Couldn’t have been more unfounded, there’s a real diverse group of ages that use it. It has a nice lively feel.
Check in/out was really easy. The Reception is manned 24 hours a day. The staff all seemed really friendly, always happy to help. They do charge a $20 bond fee, when you check in, which I didn’t quite get my head around. This is returned on check out. They organise regular shuttles to the airport.
The room itself was clean, comfortable and spacious as was the bathroom. There was a kettle, tea/coffee, fridge and hairdryer. My room had huge sliding doors which were handy as it was hot, but they made the rooms really light.
There’s a large communal kitchen, which was well equipped. It did always seem busy though. A nice spot to chat to others. Everyone seemed to take good care of it.
As a modern place the sound insulation was better than all the other places I stayed, I slept very well.
If you’re driving there’s not a lot of parking onsite, however there’s loads of on street (free) parking just outside.
Christchurch was super easy to find your way around, they give you a map when you arrive. The centre was about a 20 minute walk. There’s a pub next door, food was nice and a good selection of beers.

Stayed there for 1 week and was a gd stay for the price i paied would go back again sometime this year. Close to everything i needed. Just needed a fan in the room as they were warm and opening sliding door wasnt enough and couldnt keep that open over night.

I stayed for 3 nights in December 2018. The place has nice rooms with enough space. The main building has a laundry room, TV room, atm, tours, etc. I printed a couple of documents and it was cheap and very convenient. The bar outside the hostel offers discounts on tap beer for anyone who shows their room key.
Just two downsides: dorms don't have plugs next to beds (at least not for the upper bunk beds) and it is a bit of a walk to get to the CBD. I didn't mind the walk as I like to do it anyway, but it is not close if you want bars and restaurants at your doorstep.
