Very mixed bag experience with this cabin. First, the host required that I send photos of my debit card prior to receiving the directions to the cabin for incidentals. While I understand the need for a card on file, email is not a secure form of communication and I am uncomfortable sending sensitive information using that avenue. The host was unable to provide an alternative so my choice was to figure out an alternative method on my own or lose my money and lose out on the trip. Luckily I was able to send it via secure document.
I highly suggest reading the rental agreement very closely and being prepared to do significant deep cleaning at the end of your trip if you want to avoid getting charged. Evidently this cabin is not cleaned or inspected between guests (it's also unclear how often the bedding is washed), so guests are expected to do things like clean the toilet, mop the floors, and empty the sink tank.
If you're fine with all of that and do well at high altitudes, this could be a great place for you to stay. It was absolutely beautiful scenery, a thoughtfully built structure, and I'm sure when the hot spring is working it is absolutely lovely. Unfortunately I ended up having a medical emergency and we had to leave early, resulting in $240 worth of fees when the price was already pretty steep considering the amount of cleaning expected. All in all, just make sure you know exactly what you're in for when booking this cabin!
