Short stay housing in Rotterdam

Hey people,

We are two intern architects from Cyprus, 24 and 25 years old, who are coming to Rotterdam in the end of September! We are going to work as interns from October till mid January. We are searching through some options as we are very easy-going persons:

-    2 rooms in a shared apartment, 250-350 euros each incl.
-    an apartment for two around 600-700 euros incl.
-    we have already spoken with some other people who are looking as well, more of them interns, so if it is available any apartment of 3 or 4 people, would be ideal too!

We are looking forward for any answers and offers! Please PM if you know something or any of your friends know, or even if you are looking for roommates or you have any offer!

Best Regards!
