Mogens was a great host, and made sure we had all neccessary details before arriving, and a friendly friend to let us in and show us around, including tips for touring Copenhagen, and guidebooks!
The apartment is lovely, large and very roomy and looks like the pictures. (The rooms we slept in had one double bed and one single bed, so I'm not sure how it would work for two couples).
Being right next to the train station was very convenient for us. However, there are down sides - the street between the station and the apartment building is a bit unpleasant. From the other side - the building leads out into a lovely, gated courtyard with other buildings in the complex, and from there out into a very pleasant neighborhood, with lot's of cafe's and restaurants closeby. We reccomend staying there for your visit in Copenhagen!
