Located on the southeast coast of France, the Attrap’Rêves Bubble Hotel is a collection of transparent prefab tents that span along the Bouches-du-Rhone forest. The sustainable design was created by Pierre-Stéphane Dumas and is furnished with the comfort you'd expect from 109 euros per night. Slumber in the outdoors and enjoy the the gorgeous views just 7 miles outside the city of Marseille. [Fubiz]
