A place you have to go, despite that many people do not smile, it is filled with friendly people as well. Not a lot of people speak English however, or at least they don't like to, perhaps. But the city is beautiful, street/metro performers everywhere, which I love, and I didn't see many street-vendors, thank God. Lots to do in Paris, and very, very easy to get around with the metro system.
Insider Tip:Jim Morrison, and Oscar Wilde are buried in the Pere Lachaise cemetery in Paris. A recommended spot to visit.
