The treehouse is exactly as described. It is a unique little place in one of our favorite areas in the Wellington region. The 5-7min walk through the gardens and bush down to the bank of the Akatarawa River was a delightful surprise. For two people who grew up next to rivers and now live next to the sea, my husband and I both experienced a surprisingly strong dose of peace and calm just standing amongst the sound of the moving water and depth of view of the valley's hills, trees, and birds. The gardens and orchards also inspired us to come home and give the vege patch some love!
We are not usually inclined to opt for the non 'self-contained' AirBnB options as I tend to prefer having our own toilet/cooking facilities, but made an exception for the treehouse because of its uniqueness and location near the river. Natalie was very respectful and hospitable, and we had everything we needed. Had we been more inclined to socialise I think it would have been a lovely home to spend some time in, but we mainly kept to ourselves up in the treehouse for some much needed quiet time outside the city. I should also mention that we only stayed a very short time due to working the next day, so were not there for any meals.
As the ad says, it's not luxury but it's better than a 6 bed dorm! I'd agree with this - for anyone looking for hotel/motel accommodation, it's likely to feel a bit rustic. However for those who enjoy camping or don't mind a more backpacker-oriented style of amenities, this is an absolute gem.
