Living in Copenhagen I have not stayed in too many hotels, however I have tried the Admiral a few times for weekend business conferences.
Location:
About 1 KM away from Kongens Nytorv the location of the Admiral very good for any tourist. Furthermore many of the rooms have a nice view over the Copenhagen harbor. The hotel has a very impressive neighbour –Amalienborg Caste where the queen lives -
History and atmosphere:
The hotel was build in 1780 and was used to dry corn. In 1978 the building was totally renovated and turned into a luxury hotel. However the interesting architecture remains and thus the hotel is probably the most interesting in a historic sense. However there no compromises made in terms of comfort and the most modern features one can expect from a 4 star hotel.
The hotel has about 400 rooms that are all equipped with a phone and television. The rooms are mid size and very clean. The most apparent feature is the solid wooden construction that goes through many of the rooms giving a raw simplistic atmosphere together with the luxury.
The service at the front desk was good and professional but a little bit unpersonal.
"Pinafore" is the hotel restaurant with an international kitchen, which is very good but not fantastic. The Nightclub "Nautilus" is in the basement, and it seems quite nice. However some of my colleagues were approached by Russian prostitutes which is a problem I hope The Admiral hotel has solved since then.
In the lobby there is a small newspaper kiosk with international newspapers, and on the 6th floor the quests can use the Sauna and solarium.
All in all I can definitely recommend a stay at the Admiral hotel when visiting Copenhagen.
