I have just booked a trip to Paris this summer for me and my mum. it will be around the 4th/5th time we've been, so we have done all the touristy stuff, and i was just wondering if people could recommend anything in Paris to do other that the obvious stuff? Any less known areas to visit? Places for good second hand shopping? Flea Markets? Food Markets? We are staying in Le Village Hostel, just below the sacre Coeur in Montmatre, and would love to explore more of the city, from a non tourist point of view, if possible. Any suggestions would be great! Thanks in advance... Rosie.
