I've already found a few places that come with internet. Also, I have friends who have had landlords that never bothered to ask for visas. And they overstayed their welcome no problem. Fact is, there are tons of illegal immigrants in Germany. I'm sure they can handle one more.
you wont find any who gives you Internet access.. especially not with you nick name... but you could get prepaid surf sicks...
did not know that one could be illegally in Germany
