Experienced and effective yet fun language course

I've studied a number of languages in a number of countries (as well as being a language teacher myself), and so I tend to approach each new course with a rather critical eye. However, this course more than surpassed my expectations as I found the lessons not only to be well structured and expertly planned, but more importantly effective. Each lesson I felt I had gained a new skill in the language and, with an emphasis on practicing in class, I honestly felt more confident and comfortable interacting with people outside the class.
