room hunting in Germany

In the end of September, I stayed in Germany for a week and managed to find a room for October. Room hunting in Germany was so exhausting, the university and its services did not helped me find a flat and the halls of residence were full. They just said, you should find a flat by yourself on the internet although I did not have an internet connection so often. I bought a phone and got in touch with several people at an internet cafe, then finally found a room on Friday. It took 4 days to secure my accommodation. It was the first impact on me in terms of cultural differences. I realised that Germany is a country of 'Do it yourself' as Japan is a country of 'everything is organised'. But I would like to enjoy the difference as much as possible.
