In Copenhagen there are two huge department stores: the "Illum" and the "Magasin du Nord". I had read that H.C. Andersen had lived in a room under the attic in the latter but couldn't find any further information on it. So, one day while looking at Danish design at the "Magasin" we asked a sales lady. She smiled and sent us to the third floor.
But even though we searched the whole floor we couldn't find the room. No signs, absolutely nothing but houseware items and books. Again, we asked a sales lady for help. She nodded, smiled and motioned to follow her. Bringing us to an unmarked door, she had it unlocked and we were able to walk into the room that the author had lived in during his youth in Copenhagen.
