Turkish is a quite simple structured but still tough language to learn as it is completely different to the romance languages. While I was at TLC there were three turkish teachers wich where really nice and patient and instructed everything in turkish. I would not claim that I learnt all of the turkish grammar or that I am now able to speak turkish fluently, but I do not know anyone who learnt a language in four weeks. The course helped me to start to communicated with the natives and to lose the fear of speaking turkish even if not everything was completely right. The Turkish are really nice and open and love it if you make the effort to try to speak in their language.
So overall I was very pleased with my stay at TLC and would recommend this to anyone who wants to start practicing to speak turkish and to communicate with the natives!
