There are a lot of things about this space that are truly special. The views are stunning, the home has a lot of personal touches that make you feel comfortable... and the sauna and hot tub are both such amazing, luxurious amenities.
The cons in the AirBnB shouldn't be surprising if you've read through the listing and the other reviews, but they are distinctive and so perhaps bear repeating. There's no kitchen, and there's limited separation from the main home, which means you have to mentally be in the headspace of truly sharing noise space: there's a certain energy to that that's distinctive from a hotel room. The couch was also a bit uncomfortable, and could perhaps use tending to (or replacement).
All that said, we had a great time here. If these things don't bother you, you'll have a great time too. The benefits of this place are spectacular, and it was a wonderful place to explore Asheville from. We appreciated the unique experience we had here--it felt like the quintessence of the original AirBnB project. We would recommend it to others.
