Is Boulogne-Billancourt safe for solo female travelers?

it's really safe compare to Paris. it's close by Paris and yet it's more safe :) I've been living here since always and never been assaulted or harrassed in boulogne :) the metro is really safe, don't worry

It's the edge of Paris so you can take the Metro to the main are 20 mins away. Therefore you do have the worry of the parisian metro when it is crowded, however Boulogne-Billancourt is cut off from the hassle and bustle and rather charming by the river Seine. I still wouldn't wondering in the woods at night.
