The Goethe Institut is giving some semi-intensive German evening classes from 30 May-early July and more intensive Summer courses in Rotterdam and Amsterdam. I've taken 3 courses with them already and they are great! The teachers are excellent, put you at ease and they do not apply any sort of learning by hummilation methods you might have encountered at school.
The courses in Rotterdam are cheaper.
The Rotterdam office is within a short walking distance of Central Station.
Courses in Rotterdam are listed here:
