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.
A paradise for a rest : waterfalls, restaurants and bars (crazy parties at the top of the hills in Rosa Bonheur) As soon as the sun is shining people are going there to share a drink or a meal, lying on the grass surrounded by blazing green.
Great place to start a day with a cup of coffee from the best roasters in the city, to eat lunch, to have an aperitif with your friends and to listen to a jazz concert every weekend.
