Copenhagen - Rental Housing
Whether you wish to live in an apartment or in a house, Copenhagen has something for you. The city offers lovely, old restored flats, with lots of character, as well as brand new ones. If you own a dog, you might have a limited choice as far as flats are concerned.
Should you prefer a house, you can find opportunities both in town and outside Copenhagen. Copenhagen is a relatively small city and compared to other capitals, traffic is not a huge problem. A 20 min drive from the centre of town can take you to the countryside.
Many real estate agencies in Copenhagen deal exclusively with rentals, and some specialize in assisting expatriates.
