Save the links to your bookmarks and open daily to respond to new offers. Unfortunately, you need to translate from German.

Some of them have the option to create an account to set up a profile, which helps to communicate with landlords, exchange messages and keep track of replies. Still, because the offers disappear quickly, it is good to take notes.
