Located just above J Pippins Potions Shop is the small home office of the the Norwegian Writer and Journalist Rubin A. Eide.
While it is generally organized, their desk can be quite what they considered as "orderly chaos." From the window you can get a nice view of the Diagon Alley and some parts of London, a better view even at night time. However, Rubin keeps this office locked when they're out, not wanting their kids to mess with their stuffs.
