It's unclear to me if 190€/month is relevant to the original question, since no one seems to agree wether if that's what OP actually intends to spend per month on the trip, or if there's some hidden money that hasn't been mentioned. Anyhow, we can assume OP's financial situation is rather inconvenient for visiting France or Germany. Unless we consider visiting Mancieulles instead of Paris, and Holungen instead of Berlin.
