If you're ever in Paris, you must check out the green spaces. Our favorite is Jardin du Luxembourg. It definitely has sentimental value for us, but that is not the only thing that keeps us going back. Even when it's filled with people, we always seem to find a quiet spot. Well, maybe not quiet, per sé, but calm enough to where we can mentally block out the noise. ;)
Here are a couple photos that, of course, won't do it justice as it only shows a very small part of the gardens.
