"Posada by the Joshua Tree House came about when husband-and-wife team Sara and Rich Combs discovered a dilapidated series of buildings on the edge of Saguaro National Park, which they believe had previously been used to house staff of the nearby Arizona-Sonora Desert Museum. Despite the fact that some of the structures were missing walls and roofs, they purchased the land with hopes of creating their second retreat (the first is a two-bed, two-bath home in Joshua Tree National Park also available on Airbnb)."
