Copenhagen is the largest city in Scandinavia, and therefore has the Kastrup airport which is the home base of SAS airlines. This is handy and likely most people coming in and out of Scandinavia will be at least transiting Kastrup. The airport is very close the centre, about 12 minutes by train and metro that runs all night. Very nicely connected and a business friendly hub for those interested in business in this region.
Copenhagen itself is quite large, and due to the heritage of the city, it must sprawl outwards to preserve the old centre. This is not really an issue to most transiting passengers there only for a weekend (as I was) but it leads to interesting areas that lie outside the inner city that could be interesting for someone here long term.
Coming from Canada, the prices are not too different. The food in Copenhagen is not that great, unless you are willing to spring for a higher end restaurant. As a guy from Vancouver, I am spoiled with good fresh food for under $30. Here I am looking to pay $60 for something that may not be as good. Alcohol can be the same as Vancouver, sometimes cheaper, sometimes more expensive. Often this happens inside the same bar. Shots can be cheap, and a tray of shots can be really cheap. For example, a shot of vodka is about $4, while a tray of 10 is under $20. A low end beer can be about $10 but a decent cocktail can be the same price. Bartenders can be generous as well, even though tipping is not common.
