www.nightcourses.com its gives the one in D6, and is a bit
expensive at €265
a secondary school in my area D15 advertised their courses
a few months ago and they had a 12 week arabic beginners
course for €90.
so you could try out a secondary school in the suburbs near
you for a course.the city centre ones tend to be aimed at
business people and are therefore more expensive.
ask an arabic speaker to give you private lessons, try
mosques, or a lot of pakistanis own local shops(they speak
arabic indians don't) ask them if they would be interested
in giving you lessons.
1.5 hours * 12 weeks = 18 hours €10 per hour = €180
cheaper than the D6 place and individual attention
