My children and I spent three lovely nights at Kiwi Greenie. What an awesome and truly unique experience! The house is at the very top of the hill which gives you a nice view on Golden Bay and you can even enjoy the view from the bath tub outside (which we enjoyed even in winter). The house was always really nice and warm and it was probably the warmest house we have found in New Zealand so far.
The drive way is a little adventurous but the toilet is totally worth it (you'll figure that out once you get there ;)).
We will definitely stay here again!
