Joy place was very well kept and we had the whole property to ourselves (which we didn't expect). She gave us clear instructions on how to self check in and told us we could choose any room we liked.
We stayed in the converted garage and had ample space for all our things.
There are some bus routes close by but christchurch is rather spread out so give yourself plenty of time to get around.
All in all a lovely place for the night and close to the airport.
