Loved our stay in Christchurch! Cynthia was a wonderful host, providing snacks when we arrived, a fan for a warmer day and then fresh towels. The location is also very convenient.
The only drawback was that was that it is on the ground floor, so it isn't always 100% quiet at night. That didn't bother us at all, especially with a fan, but just something to consider if you're a very light sleeper.
