Here are two good schools on Asia side:

Montuno Dance Studio (couldnt find their web pages. check FB)

aytuncbenturk.com



And two good schools in European side:

imudance.com

depodans.com



From the list above, I would recommend IMU dance since they give
importance to musicality and technique. Also they put afro cuban
elements to their dance. Ozlem gives some rumba workshops in the
weekends as well. They also have jazz classes which is great when your
friend reaches higher levels. Also they have on2 classes after 6 months.




Depo dance is also good but I would recommend only Kutsal's classes
there. Depo dance is more crowded than IMU so your friend will find more
practice opportunity. (apart from classes, these schools have practice
session for 3-4 hours on sundays.)
