Located 2-3km from the heart of Copenhagen (which is easily done by walking), and quickly linked to the airport by public buses.
The flat is great for two persons, but could seem a little small for 4 : the second bedroom is actually an office in which you'll find two bunk beds. The living room is amazing, and the bathroom is, well, Copenhagen style : 1m² in which you'll find toilets, shower and sink. You get used to it, though.
Michael and Mia were nice, serious hosts and overall we had a great 3 days stay in Copenhagen.
