Polish - French exchange/tandem (Vienna)

Hi everyone, I'm looking for a Polish tandem in Vienna. I started a couple of months back, made a lot of progress, but I want now to move to speaking stage.

Polish ? Need it for light business reasons. I hear so many Polish-speakers in the metro

French ? I would preferably exchange with someone who wants to practice French (my native tongue), rather than English. I'm also fluent in English but they are plenty of English-speakers. Also speaks other languages, I'm flexible.

Where / When : a cool Viennese café ! Breakfast, late afternoons, I'm flexible.

Who / What : I'm a polyglot traveler, geek, design, love wine and cooking and good TV series. Addiction: magazines and newspapers
