Overall, this was a unique and wonderful experience!
With regards to check-in, instructions were detailed and easy to understand. Location wise, my partner and I had some trouble locating it (but maybe that's just our sense of direction). So, we arrived early and chanced upon the host and he was extremely welcoming. We were also able to check-in much earlier as they were just finished with the cleaning.
Although we knew that it was small space-wise, the design was open-concept , which made it appear spacious and comfortable. There was also a folder with the backstory + pictures of the construction, which we felt added a personal touch and we really appreciated it!
Other facilities include a mini-fridge and a microwave - there is no stove so cooking might be difficult, but that was not a problem for us as we had a short stay.
For the open air bath, we really really enjoyed it! The view was beautiful and it was a great way to relax and unwind after a long day.
