For those of you trying to learn Blender Cycles and render interior scenes for architecture with Blender, I just found an interesting project posted at the Blenderartists forums that might help. An artist called AniMeAniBe posted at the forums some interesting renders with the visualization of a modern bedroom. All the modeling was done in Blender and the render with Cycles. The project is interesting because AniMeAniBe shares some of the settings used in Cycles to render the scene, like the placement of light sources on the scene.
If you want to learn more about how the light setup for interior scenes like this, I recommend you to take a look on the project and settings.
