Hello I ve got a potential job on hand to move to Berlin. I have read that Berlin is quite affordable compared to other European capital. My situation is as follows: I used to live in London with an "comfortable " salary.I've moved to Vienna and agreed to take a a pay cut as I had less expenses( free rent and less bills) . The job offer in Berlin would be about Protected content without 13th month. My questions: Are they any website where I could compare electricity & Internet providers? Is is acceptable to negotiate on social benefit like holiday allowance or use of a company mobile phone?
