How many funds do I need for accommodation, living etc?
You should calculate for a room in flat-sharing community approximately 300-600 € per month. For a single flat with one room, this will cost around 550-900 € per month. Typical student areas for living are Berlin Kreuzberg, Friedrichshain, Neukölln and Wedding. Some helpful websites are www.wg-gesucht.de, www.immobilienscout.de, wgcompany.de and www.zweitehand.de.
Since you are only required to stay in Berlin during the in-house-classes (but of course are welcome to stay longer), you could book a hostel for only these two week-period. For example, see http://www.diefabrik.com/.
