Here’s a tip: the Eiffel Tower has a designated metro stop which is the Bir-Hakeim station on line 6. However, it’s a lot better to get off at Trocadéro station on the same line because the view is way better and I’m sure that your pictures will come out perfect.
Now, whenever I see a policeman on a bike, I get bothered by it. Why? I mean, what if they need to arrest someone? What are they gonna say, “Get in the basket!” ? That’s just odd.
