Overall this was the most disappointing place I have stayed with airbnb. Communication from Dustin around the booking was great, and structure itself is incredible and unique, but that's about all the positives I can manage.
The area is generally quiet and secluded, but is up the hill from a couple of houses which are either the owner's or friends of the owner's, not quite sure. There was a loud party going on there the first night with music and people shouting, until we complained around 11pm. We then had more noise from these houses the second night. It is hard enough to sleep in perspex blob which naturally has no soundproofing at all while suspended above a party, let alone experience it as "a space created to tap into your higher self, a space to rediscover your inner calm".
The entry and exit to the treehouse really is a bit risky - it is described this way in the listing, but it is not an exaggeration at all. The safety harness system I saw afterwards in the description was never mentioned.
There were friends of the owner camping immediately around the corner in the driveway. This would have been fine if they were friendly, but they completely ignored us which was odd and pretty uncomfortable.
The facilities are very rudimentary. In some cases this was expected (compost toilet etc), in others it was low effort or just not good enough for somewhere that was coming in at $450(!) a night overall. The place was dusty and a bit grimy, the sheets felt greasy and weren't ironed, the sink in the bathroom leaked, there was no mirror in the bathroom, the water supply was flaky and stopped working altogether on our last day. The host never responded to our message about this, so we didn't even have drinking water when we left.
I really couldn't recommend staying here without some big changes, which I can't see happening.
