We had a great time here. The hosts were responsive and very courteous, and the accommodation had all the amenities we required. We stayed here when it was warm and although we didn't see any air conditioning the cottage was a comfortable temperature.
The property is beautiful and only a short drive to Twizel. From there it's only about 40 minutes to Mount Cook or, if you're heading the other way, about 45 minutes to Lake Tekapo.
Highly recommended.
