Hi there!
We have just found a flat in Berlin as we are moving there next week. Some general advice: if possible I would try to give longer than three days to look.
My boyfriend filled in applications for a couple but it has been down to the landlord to go through the applications and select who they want, and we weren't picked for one but got the other. But the landlord took quite a few days to decide as he had a few applicants.
If we hadn't got the flat that we did, then Room with a Loo (English speaking service) had sent us details of flats that they had to let on a more short term basis so we could then look for something more permanent once we were there.
We also found that some agents advertised having lots of flats in certain areas then said that they didn't have anything at the moment when he rang.
Good luck with your search!
