Done in 2.71. I used the room next to mine for the floor plan and wall color, and decorated it for a teenager or university student.
I jammed out and pulled from BlendSwap for the small background items - thanks to neogen22 for the Iphone 4S, Tappi for the perfume bottles, kilbeeu for the bathroom kit, and dalpat for the stationary kit. Everything else is mine.
