(Translated) I took a two-week intensive course at the end of October as a "Bildungsurlaub" (German option to take a training holiday) and I found it a great experience where I managed to make friends of different nationalities.
I feel that my level of French has improved a lot and now I feel more comfortable speaking, plus my acquaintances in France say that they can make a difference. I really liked the teaching system and the possibility to have classes with different teachers. The building is very nice and for me very well located near the Gare de Nord. All the teachers, including the administrative staff, are super friendly and ready to help you with anything you need, and you can tell they do their job with pleasure. I think it's great that they encourage you to speak French all the time and even encourage everyone to have lunch together (teachers, students, administrative staff) to practice French.
The Wednesday afternoons offer very interesting cultural outings as they invite you to discover Paris from a local point of view.
I totally recommend this school! (November 2022)
