For the coffee, I guess I was a little intrigued at the way he poured it and the granularity that seemed to be too high. Then that percolator really seemed like old milk or water kettles found in France, but since it is about 120 years ago, I have to be cautious.
Regarding sceneries, I started to search for every places I know of. But this is incredibly time consuming and it's very hard to find the right angles in maps or other sources that match the scene in the anime.
For example, very first image of first ep isn't "Notre Dame" but "La Trinité"

Later in the intro you have a very short shot of "L'école Militaire"

In the shot, the view is cut higher, like you are on a high platform bus... pretty much the position Yune seems to be.
