They always say that Paris is the most romantic city in the world. I don not think so, though.
It can be polluted, crowed and pretty noisy around new year's eve as hell. In one hand, Paris is lovely; its streets, its fountains and its museums. You will always find something to do, a place to explore, a museums to stay all-day long. Probably that's why it is one of the most visited city in the world. Eiffel tower is its landmark for excellence. It is place you ave to visit as a foreign. the view from the top is just speechless, I loved it.
On the other hand, the line to go upstairs in the Eiffel tower is always three or four-hour long or even more.That's why I would tell you that if you really want to visit the Eiffel tower, something I don not recommend, try to avoid peek hours or just be ready to spend more than half of your holidays waiting in the line.
