If you're looking for an off grid experience, this could be the right place for you. To shower, you can boil water and use the solar shower bag; to use the bathroom, you 'flush' with saw dust; to see, you use the solar powered lights; to cook, you use a gas stove. Etc. I'd say that this experience is very similar to camping.
You can expect a warm stay inside the main room (where you sleep); fresh eggs, bacon, homemade bread, coffee and teas; a comfortable bed; and if the night sky is clear, lots of star gazing.
This place isn't for everyone - it all depends on what you're after.
