This Parisian apartment might not be the most spacious of tricked out of properties, but it's definitely got the best view: The City of Lights, as seen from top of the Eiffel Tower.
When designer Gustave Eiffel finished his tower in 1889, he built himself a secret apartment on the third level, almost 1,000 feet above Champ du Mars.
In Eiffel's time, the small room was filled with wooden furniture and a grand piano. The apartment also held a small laboratory area, which the designer outfitted with the time's most high-tech scientific equipment.
When Parisian high society learned of Eiffel's private hideaway, they began begging him for the chance to rent it out, even for a day. But it seems getting inside the apartment was as hard to achieve as owning a Nando's Black Card.
Eiffel allowed no one else to use the space. Even today, 92 years after his death the tradition continues, with the apartment only rarely opening for public view.
