My listing ( www.airbnb.com/rooms/7716963 ) is in the area of Disneyland Paris. It’'s in a pretty, walkable neighborhood, though the metro is not within walking distance (about 2.5 miles) but my partner and I believe that the nice views make up for the distance to the metro.
Regarding STR regulations, there are strict regulations in Paris center and a few inner suburbs (turning an apartment into a short term rental requires a kind of building permit, and in the center you have to buy commercial rights) but regulations are very permissive in outer suburbs like mine.
In my opinion real estate prices in Paris center are too high anyway to be worth the investment, unless the plan is to buy a pied-à-terre for your own use.
