I took twelve weeks of the intenstive classes (20h/week).
During that time I improved my Spanish very much and now I'm already able to take part at daily conversations. Started with A1 and finished with B1. I had a lot of fun with my teachers and ofter students from all over the world. Also great were the activities which they offered additional to the classes. The location is nice setteled in the heart of Barcelona and also the facility is really nice.
All in all, it was a great experience and really eficient to learn/improve Spanish and I'm looking forward to continuing the classes this year.
I totally can recommand everyone to do some classes there.
