I found this tutorial on CG Tuts+ (cg.tutsplus.com/tutorials/maxon-cinema-4d/model-texture-and-render-an-interior-scene-with-cinema-4d-and-vray-%E2%80%93-day-1/)
I decided to follow the course and here is the final render.
Render time: 10 hours
Core 2 Duo
2 GB of Ram
Not entirely satisfied, some errors were found at the end of the render.
