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.

Cité de Trévise is impressive for its quietness in the heart of 9th arrondissement of Paris. Trees, a fountain and beautiful architecture, the perfect place to spend some time.

free Jazz concerts and parties 

Very nice place where you can take your time for a coffee or eat french cooking by a Japanese chef. The design is like you're at home and there are different artist displayed on the walls.

So much inspirations in this beautiful bookstore at Palais de Tokyo museum. Hours and hours to spend there before or after a visit at the exhibitions.
