Climb your way up the escalators to the 9th floor of the Printemps department store (the Beauté & Maison building) for possibly one of the best panoramic views of Paris. You can see pretty much everything from here and unlike the views from the Eiffel Tower you’re right in the middle of the city and can almost reach out and touch the monuments around you. Go up on a sunny afternoon and take a seat on one of the benches, lay down on the fake grass lawn or have a drink and a snack at the Deli-Ciel café.
There's a few secondhand clothes stores in Paris, but always immaculately selected, expensive and fashionable. Guerrisol however is a huge, dirt cheap jumble sale. Stock seems to rotate daily in each of their four stores, and prices fluctuate on the hour. Sifting through endless rails of synthetic jackets at €3 can suddenly reveal a hidden gem.
