I can only recommend Josephine‘s beautiful apartment. You can do many things from there. Start with a beautiful view over Stockholm from the hill right on the other side of the street. Walk to the fabulous cafes and shops of Södermalm. Visit the nice playground of Drakenbergsparken. Take the ferry down the street from Slussen to Djurgarden or walk straight to Gamla Stan.
An when you come home, you will find a nice apartment with the typical Scandinavian sense of design and cosiness.
