You finally found an apartment in Berlin but now you are wondering how to register your apartment (Anmeldung) in Bürgeramt as quickly as possible? Without doing so, you may not be able to open a bank account, sign up for internet for your apartment, etc.
Way #1
The fastest way to book an appointment in Bürgeramt is over their Website: https://service.berlin.de/terminvereinbarung/.
Way #2
Call 115 in the morning (around 7 am or 8 am). You may be able to get an appointment on the same day.
Way #3
Send an Email to any Bürgeramt and ask for an appointment. Note: This is usually how the founder of Booka Local gets herself an appointment. 🙊
