I stayed at Heather's place over the tail end of a weekend to walk the Tongariro Alpine Crossing with my partner and friend. We found their bach to be well sized for a group, comfortable and well equipped.
Its location in the National Park Village was prime, it made getting to and from the shuttles we needed to take incredibly easy. On top of that, the spa after a long walk was just what we needed and really topped off our experience staying there.
It might not have the slickest decor but in terms of comfortability and value for money, I doubt we could have found better.
Highly recommended.
