After a very careful research I have chosen this school and it was an absolutely right decision! Everyone, literally every person in the school takes very good care of you.
Teachers are professional, extremely patient and take all time needed to make sure everyone is performing well. There are various exercises for French grammar, vocabulary, oral and written understanding/writing. And there is also a lot of speaking of course!
Groups are comfortable size of 6-8 people and everyone has enough time to ask questions and practice some talking.
Every Wednesday there is an after-lunch walk with one of the teachers, in Paris for those who want to see some historical and cultural places, hear stories and yes, speak even more French in a friendly atmosphere.
Price is competitive, but not too high and definitely not high enough considering their level of teaching, attention and service overall.
Personally I spent there 5 weeks this summer and improved my level of French significantly, specially the speaking part. I'm very pleased with the results and considering going back for some more courses. (July 2021)
