We stayed here as our flight from the Cook Islands got in too late to get a connecting flight to Christchurch.
We were both really impressed with the price, location (courtesy bus from just outside the terminal building), cleanliness and how quiet it was considering it was right near the airport.
Their is a Macdonald's in walking distance for a quick bite to eat. The courtesy bus runs 24 hours so can ship you to early morning flights. Also breakfast is included and worthwhile.
