Seems that they closed their Geneva's office... at least, I couldn't find it in the web-site

"THE BEST LANGUAGE SCHOOL IN THE AREA! Very friendly teachers who help you with anything! I’ve spend there three school years, had every year a different teacher and loved it every time. I made there many friends, we played theater, read books and had a lot of fun. Mostly French, but also English, Spanish and German taught always by native speakers. Classes all day, free parking, reasonable prices, preparation for exams, small classes…GRETA IS GREAT!"
