If you want to list up your plan with something vintage and authentic in Paris, i would highly recommend this place”Flea market Saint Ouen” or “Marché aux puces de Saint-Ouen”. It’s not situated in the center, but the metro can easily take you there.
Seriously, I don’t know how many “Wow!” I said during my visit. This market is open on the weekend and Monday. I went there on Monday, and it was perfect, there were not much people. The sellers were so nice, they let me take many photos of their shops. And here are some of my shots, let’s take a look!
Métro : Porte de Clignancourt, line 4
Open hours :
Saturday – Sunday 10.00 – 18.00
Monday 11.00 – 17.00
