This place is amazing. It's totally cut of from the outside world, nothing for miles in either direction, which is exactly what we needed on our final nights rest during a south island road trip.
Geva and her husband Tim were really lovely hosts and built/decorated the wagon by hand! (This'll be even more impressive when you see it)
The wagon itself is a couple minutes drive from Geva's place, so you get your own space for the night. It's the cosiest little place that even has it's own stream at the back and an outdoor makeshift hot tub! It's more geared up for a romantic getaway under the stars, but I went with my friend and that made the experience even funnier (we were offered the option of adding champagne and a bath bomb to the evening - Now, I'd say we're close friends, but we're not THAT close)
The wagon also has all the amenities you could need, like a fridge, kettle and wifi that worked like a dream. Would definitely recommend this place to anyone planning a trip to the south island - was most definitely our Airbnb highlight of the trip :D
