I had the pleasure to visit Copenhagen for a few days. One of the hotels I stayed at was Marriot at AC Hotel Bella Sky Copenhagen.
Just look at the pictures. It is worth a visit and stay at. Do I have any complaints? Maybe a slow internet connection, maybe that the hotel is not at walking distance from Stroget. However its close to the Metro. Only a few minutes to the restaurants using the Metro. To conclude, I am glad to recommend this hotel.
