The real homes of real people in The Jungle refugee camp, Calais, have been listed on Airbnb. Book one before they're destroyed by the French police. All the money raised from bookings will be donated to the Help Refugees charity.
Update: Unfortunately, Airbnb consider the Jungle too dangerous a place to list homes, which is exactly our point. So you can't book accommodation through their site any more, but you should still donate directly because nobody deserves to stay in these dire conditions.
