Getting around in Copenhagen is very easy. You have the S-trains, the Metro and an intensive net of bus lines. Besides that, is is easy and safe to get around on foot or by bike. "Bycyklen" (the City Bike) is a free, coin deposit besed means of transport in the inner parts of Copenhagen. If you want to rent a bike, you can search for rental companies here.   

It's not recommendable to bring your own car in the cite centre, since there are many pedestrian- and one way streets and it can be very hard to find a parking spot.
