Nikos is the most suitable teacher for someone to learn German correctly, easily and quickly! Especially if one plans to work in a German-speaking country, I believe there is no better teacher. I have been taking lessons with Nikos for a year now and I have nothing but the best to say. His help, persistence and patience in every lesson motivates you to try more and more, for yourself! It emphasizes improving pronunciation so that one feels more comfortable speaking German. He explains the difficult German grammar as best as possible, bringing it to your level and answering all your questions. By grading each part (oral, written, listening) he sees where you are falling behind and sticks to it. Many, many positives. And only positive!! Niko, thank you so much for helping me get this far and I really wish I could get to C2 with you as a teacher!!!!!
