This is how you find a room
DUWO offers rooms in four ways:
1 - non-self-contained rooms with a vote-in via Upcoming vote-ins;
2 - non-self-contained rooms without a vote-in via Offers ROOM;
3 - self-contained rooms via Offers ROOM;
4 - guaranteed rooms for (usually) foreign students via Accommodate.
First, find out which listings you can respond to. You will automatically end up on the proper page. Are you looking for a room for just a short period, f.e. for an internship, then have a look at Other offers.
