I don't know if this is permanent hotel policy, but the staff wouldn't allow any early check-ins at all, as a result of which about 150 people all started checking in frantically at 3:00. The lobby was absolutely packed all afternoon, it was a nightmare, and once check-in opened, it took me an hour and forty-five minutes to get a key. Then the elevator wasn't working, so by the time I got into my room, it was 4:55. The hotel is clean and the area is convenient, but if you arrive in CPH before 3:00pm and you would like access to a room to rest/shower/redirect, consider other options.
