I highly recommend staying Chao's place when exploring Christchurch. The townhouse is located in a quiet neighborhood, in the city center, and within walking distance to all major attractions (the botanical gardens, avon river, etc.). The unit itself is well-equipped with everything we needed, including a full kitchen which came in very handy. The Wifi was great, it was clean, and the check-in process was seamless.
Highly recommend - thanks Chao!
