My family (2 adults and 2 kids) stayed in Freja's apartment for a long weekend and really enjoyed it.
The apartment is bright and spacious with a very nice common area - kitchen + living room, with a comfortable sofa ;-)
Furthermore, the apartment is nicely located, close to supermarkets (Netto, Irma), bakery, and harbour bus stop (very practical and pleasant to get from Islands Brygge to Nyhavn via the canal).
They will definitely stay there again next time they are back in Cph!!
