We were there for a 4 day "layover" on our first trip to Ethiopia. It was amazing to see the historical stuff that's just around town. Kind of like walking through Caesars Palace in Vegas but it's the real deal
. As mentioned, Eifel Tower was awesome to see in person. ND was very cool as well. While the subway was easy to use, we rarely used it. We walked that whole city. From our hotel, which was down by ND, we walked up past the Louvre, up along the canal to the Eifel Tower, over to the Arc de Triomphe, down Ave des Champs-Elysees, and made our way back down to our hotel. Tons of walking but worth it if you're healthy and have a good pair of shoes.
Couple things I will note, many of the people in France are the stereotypical stuck up asshole. I've never been pushed from behind as many times as I was in Paris (they don't ask you to step aside, pardon them, etc...they'll just shove you out of the way). If you don't know any French, I'd suggest you learn at least a little. When we went we knew nothing (it was only a layover after all) and they'd come to seat us for dinner/lunch/breakfast and start talking to us in French. When we told them sorry but we didn't speak French, they would give us a stuck-up huff and walk off. They wouldn't come back to us for 20-30 mins (often seating people that got there after us, but spoke French, before us) and would act like we were putting them out because we wanted to eat there (mind you, they spoke English just fine). If you've just flown 12 hours and are exhausted and starving and want something easy/quick and go to McDonalds, don't get your hopes up when they offer you Fry Sauce...it's f***ing mayo...that was a serious let down.
So, awesome to see all the historical architecture, famous landmarks, and just the general atmosphere of the city but the people really killed it for me. I've been to places all over the world and have never come across people that are more stuck up and rude. I don't plan to ever go back. I have heard similar stories from many people as well. I have a girl that works for me right now that went and lived in France to go to cooking school. She said if you get outside of Paris, the people are very nice, but within the city she agreed that they were very stuck-up and she speaks French.
