In my opinion, Nikolaos is a highly experienced and efficient teacher. He has helped me become much more confident at work. I am a hotel manager, and English is the most important tool in my profession. Nikolaos has helped me significantly improve my fluency and expand my vocabulary for various aspects of my job. What sets him apart from other teachers is his ability to bring together ideas and facts from different fields, while ensuring that I spend a very large part of each lesson speaking. I wholeheartedly recommend him.
