Josh's "Tree House" is a good choice for a couple or family staying in the Asheville area. The house is 10 minutes up a winding, hilly road, midway between downtown Asheville and an entrance to the Blue Ridge Parkway. We took advantage of the proximity and spent time in/on both places. It is easy to get downtown, but don't try those roads after visiting Asheville's amazing breweries! We loved shopping and eating in Asheville (Wicked Weed and Buxton Hall were both excellent). We also went to a Tourists game (minor league baseball), which was a really fun experience for our family.
The Tree House is exactly as described-- it is a relatively small place with basic furnishings and a cool whirlpool/shower combo bathroom. There isn't really space to hang out outside, other than a small balcony. This might be a problem for families with small kids. Our boys are 6 and 9, and we had absolutely no safety concerns. I would recommend this spot for those who prefer quiet!
