The usual course of action is flat sharing. Rent is then a bit more reasonable. In London you could find rooms from a few hundred quid pcm, then depending on location the sky is the limit. That was the most expensive city in Europe, pre-Brexit.

For a room or a whole apartment?

Rooms range from 500 to 800 in amsterdam, I just checked the facebook group and the first post is student housing available for 317 euros.
