Looking for accommodation on the spot
The accommodation situation for students is generally difficult, as cheap and furnished accommodation is hard to find. If you prefer private accommodation, please refer to websites such as: http://www.immonet.de/ https://www.immowelt.de/ https://www.immobilienscout24.de/ http://www.wg-gesucht.de/
It is also worth buying local newspapers on Wednesdays and Saturdays and reading the advertisements for accommodation. It may also be helpful to place your own request in a newspaper instead of just responding to advertisements.
