We had the privilege of staying at the Cozy Oak Cottage for a month in May. We would have been ok with not ever leaving. Out of all the AirBnB's we've stayed in over the years, this one has been the best experience we've had.
The place itself is unique and beautiful; an oasis of plants, birds and animals tucked away on a side street that's central to everything Asheville has to offer. The back porch is a wonderful way to start the day or end it watching the fireflies through the heavily forested backyard. We were lucky enough to have Randy around while we were there and it was wonderful getting to know him and his ever faithful pooch, Buddy. The care and thought that he has put into the place makes it feel completely magical.
If you are considering a stay near Asheville, we highly recommend staying at Randy's.. if you can manage getting a reservation! :)
Also, take advantage of his AirBnB "experience" (hike) to Catawba Falls. It's a great one!
