My husband and I will be in the Provence area in October for about three weeks. We've booked two homes in different parts of Provence - Luberon and the Var. We have about 4 extra days at the end of our stay and I've read (in the NYTimes and other publications) that Marseille is an up and coming, interesting City. My huband and friends we are traveling with aren't so sure. Can anyone advise me about what makes Marseille so special. Is it work 4 days? Thank you so much.
