I liked Absalon. For me it was a good choice, value for money.
First of all - great location. Handy for a railway station and to the Copenhagen city center. Main places of interest, including Tivoli Gardens, National Museum, Glyptoteket, Tourist information center and others are in the walking distance.
Full buffet breakfast was served in a ground floor restaurant. It was hearty and included among others such danish specialities as several sorts of local bread, sour cream, scandinavian herring.
Hotel has a nonsmoking policy. At least on our floor smoking was forbidden.
Downside were very small room and bathrooms. We stayed in an economy budget room. Furnishings were simple and old. Washbasin in a room. Toilets and showers - outside in a corridor.
They had a coffee machine in a lobby which provided free hot drinks for guests. I think however that the staff should pay more attention for maintaining it, as the machine tended to be out of order from time to time and required to be cleaned of waste.
