My wife and I stayed here for 3 nights and had a great stay. It is clean and warm and the shower is awesome!
Definitely need to have a car whilst in Christchurch as it is 45 mins to centre.
One thing that would make it better is if there was a curtain/blind over the back door as this is right next to the bathroom.
Check in is super easy and the instructions about check out for the next guests are clear and reasonable.
