"Free Paris walking tour 3.5 hours" The Free Tour meets daily at 11 AM, 1 PM and 4 PM in front of the fountain at Place Saint-Michel in the Latin Quarter. To get there, take Metro Line 4 to Saint-Michel .The tour is completely free, you only tip your guide at the end.  The guide (Jen) was very good and also most amusing.It's a great way to see Paris. Would Highly recommend this Tour to anyone visiting Paris for the first time.
