In addition to the above nearby accommodations, there are at least 100 other good hotels in Copenhagen that are only a few bus or subway stops away. Making your way to Nørreport Station from any of them, you will only have a less than a 10 minute walk to the venue. Do make your reservations early, however, as hotels sell out quickly in Copenhagen during the summer months.
