Absolutely perfect in every way. Louise was quick to reply to any questions, the cottage was in a great location, and it had everything we needed. We were particularly impressed with the little touches - a handwritten note, bread in the freezer, jam in the fridge. We couldn't have asked for more for our stay on Waiheke.
One tip to other travelers - we used Island Taxis for our trip there and it cost $55, but Wai Cabs on the way back was only $30.
