The property’s rustic and cute, tucked away in a canyon. The beds were really comfortable. I enjoyed the sauna. The rooms aren’t that well-maintained (mold in the bathroom). They had a big event with maybe a hundred people and a loud DJ late into the evening (couldn’t drown it out, even in our room). It seems like it’s become a place for community events which is great, but not so great for the guests. Some of the amenities they advertised were out of order. It’s unique and has a lot of potential but wasn’t the place for us, especially at the price (over $300/night).
