I'm here at the moment, for a decent apartment in the city expect something between 1000 and 1500. Of course the prices will drop quickly if you move away from the center.
If you have a car you might need to rent a parking spot (about 200 to 300 a month) or you can do the public parking but expect to take a walk that can cost you 10 mins.
Water/electricity is fairly cheap; I'd say around 200 for everything for your whole family.
Internet is ridiculously expensive I pay 70 euro for a 14mbit line lol.
If you have any questions just drop me a msg
