Henriette's posting and Leo's question inspired me to do a Google search: "sprachcafé AND fluechtlinge". Apretty long list appeared, see results here: ****://bit.ly/1Wuud9C
You could refine your personal retrieval in adding your present inhabitancy e.g. "sprachcafé AND fluechtlinge AND Berlin".
I hope these suggestions are beneficial for you.
Kind regards, Jan
