5 stars as this was the most incredibly beautiful stargazing experience I have had for a long time if not ever. I am planning my next trip back already! So glad to have lucked out and stumbled upon this gem of a location. See you on my next NZ adventure! The private bay with a sandy and plentifully shelled beach was a huge hit too.
Downsides were that the off-grid house was not as comfy as this city-kid is used to, and the hourlong drive from central Martinborough became very remote - no cell service (but there is good wifi at the house) and the slides on the road were a little hectic for a 2 wheel drive van.
