Couple from Munich (25/26) looking for accommodation in Rotterdam for a 2 year stay

We are a young couple from Munich and we will move to Rotterdam in the end of August as we are both enrolled for two year Master courses in Rotterdam. We are looking for a flat to provide us with a base from where to organize our life in Rotterdam.

We are reliable, orderly and social persons and will both be working during our studies. As an additional security for you both of our parents would serve as financial guarantee. 

Our studies will start at the first of September, but as we would like to to move there a bit before to get everything sorted, we would rent the flat from August on.
