Lisa & Karl's apartment is great. Its in a residential area near 2 metro stations and is walking distance to many parts of the city. We only met with Karl but he was really friendly and showed us around the flat when we arrived. They have prepared a list and map for their guests of their recommendations for local places and things further away. The apartment is very cool, nice and light with nice furniture and big screen TV. Don't hesitate to get in touch with them if you're needing somewhere to stay in Stockholm.
