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.
Villa Léandre is a very good place to relax and have a calm moment. Small village street in this charming neighborhood at the foot of Montmartre. It is a parenthesis of sweetness that makes the charm of our city.
