My Spanish for your German (Madrid)

Hallo Alles! :)

I am looking for a German speaking person for a German-Spanish language tandem (though I am also bilingual in English and French, so I can tandem in those languages as well).

I have a B2-intermediate level of German and I am willing to gain fluency in my conversation skills.
I've given Spanish language classes to high-school students so if you are struggling with grammar I can give you a tip or two ;)

Grüssen!
