aye. there's lots of pockets of turkish, english, spanish, arabic, italian, chinese, indian, african etc who can't speak much german but still live here. it can be done if one is so inclined (i lived in prague half-a-year and barely spoke 20 words). plus many germans consider it a badge of honour to be able to speak english.
and german's a dying language anyway, looking longer-term.
still after saying all that, right now anyone who can speak it has a considerable work & flat-seeking advantage.
regarding other cities, berlin's now roughly on-par with most of them...it's no longer 'poor but sexy'. far cheaper rents can be found in less trendy cities like Leipzig, Bremen, Magdeburg, Karlsruhe and the hundreds of Kleinstädte like Pirmasens, Hameln, Meißen and the rest.
berlin's now more like hamburg, münchen, köln in terms of affordability.[/QUOTE]
Really? Would never have thought that. Especially Munich.
