Peter and Sharon are very nice hosts. Their home is big and lovely. It's very close to the airport and Peter came to pick us up (for a nominal charge).
We had an interesting conversation with them for a good 1.5 to 2 hours and Peter gave us very nice suggestions for our trip.
It was our first night in New Zealand and we were very happy to stay at Peter and Sharon's home.
Sharon even gave us late check out facility although she had to go somewhere.
All in all, a great stay. If you're going to Christchurch, do stay with Peter and Sharon.
