This 18th century duplex in Saint-Germain-des-Prés is the epitome of Paris style and elegance, and the exquisite attention to detail of their interiors. A collaboration between Claude Cartier Studio and Simon Pesin, this beautiful space is a mix of traditional architecture and modern furnishings….indeed a confluence of the arts.
