Looking for apartment for 2 or 2 rooms near Erasmus

Hi, we are looking for apartment or 2 rooms for my son and a friend of him who make the same studies at Erasmus University. they are both 21 years old and are quiet and serious. It's for end of augustus till end of december. It's us, parents who pay rent and charges and we can send all proof of incoming revenues. They are Belgian and study at the U.CL. university In Louvain-La-Neuve. Thanks for your consideration.
