We stayed at Vibeke's apartment for 2 nights during the weekend and we loved the retro/bohemian decoration. Also she has plenty of cookware and we could use the log burner.
Not only that her neighbours and her helped us with a scam we had with a taxi driver from Oslo airport to her apartment.
The neighbourhood is tranquil and friendly atmosphere, very recommended.
Oslo city centre is 9 stops away by bus with several lines to different areas.
