9. La Maison des Champs Elysees

Location: Paris

Designer: Maison Martin Margiela

Price: from $890 per night

Descirbed as a "carbon cube" by the designer, this entirely black suite is as sexy and mysterious as you'd expect from the avant Belgian design house. When one Maison meets another, things get quite surprising. Named for the "curiosities case" that fills an entire wall of the suite, this room stays one step on this side of macabre simply with an articulated sense of taste.
