The Flea Market in Jaffa is one of the more charming places to walk around.  The real day of activity is Friday, when all the shops take out their merchandise on to the street.  French sofas, an old shawl, a carved oak table and pillow covers from India, Judaica, old enamel kitchenware, antic clocks and what not, you can probably find anything here. 

The prices aren't as low as you might expect and haggling is a must (watch Monty Python's "Life of Brian" for some haggling guidance), but you don't really have to buy anything to enjoy your visit.  When you are there, you can stop for a coffee or a bite to eat in Pooa or Shama (3 Rabi Nachman St. 03 518-7599), charming little places in the very center of the market's allies.
