I've tried several German tutors in the past, and Malte has been seriously the best. I'm at beginner level. He made sure suit my needs (emphasis on speaking & correct pronunciation). Malte was super patient with me, while making certain that I fully understood grammar & sentence structure. Plus, since he is a native speaker, he taught me so many local idioms and fun, useful cultural facts that can't be taught in a book. I know that with past native-speaker language tutors, there's always somewhat of a language barrier - but Malte's English is near perfect! I would give more than 5 stars if I could!
