Stop reading and book this airbnb.
This is a hobbit hole. Full stop. It is a round building with a bed in it. There is no electric, but there is every other amenity. The listing calls this "glamping." The only part of camping involved here involves turning on lanterns and lighting a fire. The listing is under 20 minutes from Hobbiton.
I expect this listing to end up on the front page of NZ's airbnb page. This airbnb is _that_ good. The only reason it isn't there yet is because the hobbit hole opened January 2018. Book this amazing place at once.
