Assouline is a bookstore brand based in Paris, in Saint-Germain-des-Prés and in other cities all over the world.
This library fits perfectly in the cultural and intellectual mood of the district (one of my favourite!), here you can find books about art, architecture, fashion and travel mixed with luxury items, furnishing, leather goods, candles and more.
The decor is pretty unusual for a library, it seems at first glance more like a gallery, in which the artworks (the books) are shown with an extra care in details.
... I have to say, it's all about the details!!!
