Jordan cave on CouchSurfing.com

Ghassab Al-Bedoul, 42, offers up his cave in Petra, Jordan, for visitors on CouchSurfing.com. It looks like a fantastic experience. In the four years he's been registered on the site, Al-Bedoul says he's hosted more than 1,000 people. 

From CNN:

The cave, which is no larger than 150 square feet, is uniquely modern. A row of solar-powered lights, a gift from a couch surfer, encircles the front of the cave entrance. When the sun sets past the Petra mountains, they are the only visible lights.
The outside of the cave is hard stone, but Al-Bedoul has done some decorating on the inside. The roof is painted black with stars circling the room. Candlelight glows just bright enough to see some of the traditional Jordanian paintings he's placed inside; not included in that collection is the large Bob Marley poster near the cave's entrance…
When asking Al-Bedoul for the washrooms, he points to the mountains, and says, "far away please."
