The Flea Market is a market for second hand stuff. All weekend there are markets around the city, but twice a year they hold this much more impressive event. It sells everything you can imagine. From clothes, books, kitchen items, antiques ... If you go early you can find real bargains. A friend of mine bought a bike in pretty good condition for 20€. He also bought a nearly new cooktop for 5€, skates for 5€, a shelter for 8€. It's worth getting up early that Sunday just to enjoy the atmosphere, the colours, the smell of flowers and food stalls and curiosities that you come across.
