The room was comfortable, modern and clean. We received a free upgrade and had a nice view of some water and construction work.
Some of my family was staying closer to the center of town. They booked earlier and rooms there were no longer available. Their room was not nearly as nice and they paid slightly less then I did. As I saw there room, before I got to mine, I was quite pleased with my room. The Copenhagen Island Hotel was pretty convenient to a public transport area and was only about 10 minutes or so walk from the main downtown area.
The breakfast buffet, not included in the room price, was pretty good, although it was not cheap.
