We absolutely loved staying with Tania and Gordon (and Lucy their lovely little dog). Gordon came over to say hello when we arrived late one night, and was quick to offer any assistance we needed. The house itself is attached to the main house, but incredibly private. It looks brand new- with everything clean, tidy and easy to find. It is located on a quiet street a 2 minute drive from the town centre, and is conveniently located close to Mount Cook and Lake Tekapo- which makes it great for day trips to both. The free range eggs, fresh milk and other breakfast supplies were very appreciated.
We would highly recommend staying there, and would happily come back.
On a side note, if you're looking for a good pub meal in town, try the Ministry of Works- we loved the food!
