I love to go to this library and often work there. It is very peaceful and the setting is beautiful. The library is a mine for books about design and architecture.
Le Barn crosses the bucolic charms of a French country home and the design chops of the ever-growing hip boutique hotel scene in Paris, providing a chic and relaxing base for Parisians and visitors, less than an hour out of the city ! So cool.
It's always good to check out what's happening in Fondation Cartier. They have lots of really good exhibitions of modern art, and the gallery itself is very beautiful. Perfect for seeing works you already know as well as discovering new artists and inspirations.
