Arriving at the Island Hotel after an overnight flight from Seattle, we were happy to be checked into a very quiet and comfortable room right away. Our room had triple-glazed windows and a solid door, and we slept soundly every night.
The hotel was easy to find, as it is right on the ocean next to the Fisktorvet shopping center. It is a pleasant 20-minute walk from the Central train station. Just walk from the station to the ocean and turn right, then walk along the ocean to the hotel.
The hotel isn't really an island in the usual sense. A pier leads from the road to the hotel entrance over a 20-foot moat.
Bicycles are on a pier next to the main entrance and can be rented for $20 per day. I highly recommend renting bicycles at least one day. Copenhagen is world famous among city planners for its bike paths, and we went all over Copenhagen on our bicycles, and then toward the airport to see the windmills up close.
Our room had a high-tech nightstand that included an automatic floor light with a motion sensor, an excellent little reading light, and a room light. The room had a view of Tivoli so we had a great view of the fireworks. There was a refrigerator for chilling the Danish apples we found on wild apple trees all over Copenhagen. The floor was dark Danish wood and everything was spotlessly clean.
The hotel also had an amazing pool in the ocean with a sandy beach area overlooking the pool nearby. Everyone at the front desk was helpful and professional and spoke many languages, including perfect English.

We stayed here when the Copenhagen Strand lost our reservation and had nothing for us. They took responsibility, and paid for our cab over to the Copenhagen Island.

The hotel had just opened, and they gave us a room right away at nine a.m. The facility is lovely and modern, and has probably the most comfortable hotel bed I have ever encountered.

It is, as people have said, a bit of a hike to the city center, but it's a pleasant walk. You can also get the tour boat of the city from the Marriott, which is about a (long) block away. The Copenhagen Island is right next door to the Fisketorvet Shopping Center.

Very pleased overall.

I got a good deal through expedia which more than made up for the fact that the hotel is not right in the middle (and I'm glad it wasn't actually). 20 minute stroll or 7 minute cycle (800 metres) from Tivoli Gardens along the river so it's not miles out and you don't get city centre noise. Request a river view and make use of the hotel hire bikes, but get up at 7.00 am to make sure you get one as they don't reserve them. Rooms are compact but clean and Danish design style. Not the broom cupboard that some have portrayed. AC in rooms but not required as temp was a pleasant 25 degrees for the 4 day stay.

My wife was disconcerted by the thin clear glass strip in the bathroom wall which allowed a toilet view! Solved with a strategic strip of toilet paper! Bath and shower excellent. Wireless internet signal weak, but reception provided free cable, so no problem.

Staff very friendly and informative. We used the water taxi to do the sights which leaves from the wharf outside. The service stops at 6.00pm or so, so don't plan on coming back late by boat.

Good and plentiful breakfast spread.

No room service after 11.00pm, but the large shopping centre next door had shops to buy soft drinks and snacks which we kept in the room.

Overall, a nice new clean hotel and none of the reservations I had before arrival proved a problem.

Nice clean, new, modern hotel. There is a train station nearby and a shopping centre. The walk to the city centre is rather long and boring, try a taxi instead unless you like long walks like I do... Location is in between office buildings. At the back, views are nice, at the front busy road and views of train tracks and buildings, not really inspiring. Rooms moderately sized. Beds were good. I talked to four people staying there, and all of us were annoyed by the little blue lights next to your bed that stay on during the night. Wifi reception in the rooms was poor according to one colleague. Breakfast nice, good choice and quality.
