Well, there's the Commune By the Great Wall but I don't recommend it except for a daytrip for architectural professionals, students, and afficionados. Why?
1) Bad service. Likely this will be mentioned on Trip Advisor.
2) Isolated, captive for meals.
3) Way overpriced and poor value
4) Is by Badaling Great Wall, which is the most overtouristed, overdeveloped, over-reconstructed, and therefore lackluster section.

I can't think of any other "luxury" property in close proximity to this or other, better sections of the Wall. There are some downmarket places. And if you're into roughing it, there are camping-on-the-wall trips offered, though June wouldn't be my choice of months for scheduling outdoor camping in the Beijing area.
