I am starting the A2 level in August with the Klubschule - semi-intensive lessons scheduled on Mondays and Wednesdays at 2000, and we have a great teacher. They say it's all about the teacher
. Our A1 class was also small, and despite the few nationalities, we do gel quite well. 3 of us will now be moving to the A2 course, which is starting in August.
Alternatively, I can ask my tutor if she is happy to give you private lessons - she is a great teacher - patient, speaks 3-5 languages (including English), and happy to move to English to explain the grammar. She lives in Wettingen. We easily became friends after 2 sessions, and often have our kids play together
Let me know if you are interested, and I can give you more info by pm.
