Had a great stay at Morten's apartment. It looks just like the pictures and despite Morten not being there when we arrived, he provided precise directions on how to get to the apartment and collect the keys.
It is far out from the city, but the ferry port is a 2 minute walk away although it only comes every half an hour. There are also buses that take you into the centre or if you're feeling lazy, 181DKK via taxi.
All in all a great stay and good for groups.
