Stunning location on Lake Ohau, which is off the beaten track and very peaceful. There are several other houses around, so it doesn't feel creepily isolated or anything. Definitely stock up on food and drink in Twizel, or before that if you want a big supermarket. We drove up to Mt. Cook one day, and the next did a hike nearby following a track off the main road that said it was 2km to a bridge. We didn't see another soul, and it was a gorgeous sunny day. As I said, a very peaceful spot. Adrian leaves detailed instructions, as well as a lovely bottle of wine, and we really enjoyed the fireplace. There is a small TV (I think you can Airplay on it), but we spent the evenings playing Scrabble and stargazing. Highly recommend this lovely spot!
