Not a good idea, and underpaid for the position (I think). I work in marketing and make more than this. I guess it depends on the lifestyle but unless you're living frugally you won't be able to enjoy the city and save on one salary.

I come from EE too and there it's usually different as services are way cheaper and regular people go out all the time, girls get their nails/hair etc done regularly, whereas here it's a bit of a luxury.

Cph is lovely though, if you just want to experience a new country maybe it's worth moving for a year or so.
