Nice place. Quiet, comfortable, and all the major amenities provided if all you need is a place to crash the night before a morning flight out of Christchurch. They were also offering a $10 ride to the airport, but I declined because I had a rental car.
There was a bit of a language barrier (hosts only speak Mandarin), but they were clearly accustomed to dealing with this issue and had signs, as well as a cool translator gadget that they used. I interacted with the older lady. She was super sweet and provided a very unique and tasty breakfast, and made her best effort to make conversation over breakfast between her translator gadget and my shabby Mandarin.
All in all, great place. I would definitely stay again if I need to catch a morning flight out of CHC ever again.
