Berlin consists of a number of boroughs each having their own unique style. Some of the more popular areas include Kreuzberg and Prenzlauer Berg. Most of the international schools are located in the West of the city. British oriented schools are located in Charlottenburg and Spandau and the American oriented schools are located in Dahlem and Kleinmachnow. If you are looking for long-term accommodation you can search for rentals at www.wg-gesucht.de. They offer shared accommodation, single and multi-room apartments as well as houses. Use Google translator to translate the page for you if you don’t speak German. Another option is conducting a search on Craiglist Berlin.
Landlords will typically require copies of your last three payslips, a letter from your current landlord, Schufa (a letter with your credit score) as well as copy of your registration paperwork. If you plan on staying in Berlin for longer than 3 months you will need to register with the local Public Office or Anmelden. The Public Office you register with will depend on where you live. You will need to bring your passport and a copy of your rental agreement to the Local Public Office to register.
