Berlin: The Das Park Hotel is a series of individual hotel room pipes, set on a beautiful flora-filled backdrop just steps from the Danube River.
Although this is a one-of-the-kind hotel, there are now two, one in Austria, Ottensheim and the other near Essen in Germany.
Each 6.5-foot in diameter pipe features wall paintings by Austrian artist Thomas Latzel Ochoa.The rooms are outfitted with a bed, lighting, and other furniture, even a small charging station for gadgets and gizmos.
