Addition to my earlier Montfermeil post:
According to this article the house on the left in these photos is indeed the location of the inn called “Au rendez-vous d’Austerlitz” in Montfermeil where Hugo stayed on his way through Montfermeil and which he turned into “Au sergent de Waterloo”. I don’t know what their sources are because I didn’t see any mentioned but since this was pretty much my guess too I’m willing to accept it as truth. xD Also it helps that I’m always happy to find out that significant canon era buildings still exist.
So yeah, I suppose we could say this is pretty likely to be the location?
Actually… you know what that photo reminds me off?
…. in fact this looks so similar that I’m pretty sure they must have used this place as the model :O
(although idk what’s going on with the ruins on the right, there should just be an open square there. Maybe they only had that one photo but didn’t know what the surroundings were like?)
Wow, Shoujo Cosette… you keep surprising me
