When I finally get my Index I can't decide if I want to set up my base stations in my bedroom or my living room.

>Bedroom would have a rectangular space of 5'x9' uninterrupted by any furniture
>Living room would have a rectangular space of 9'x12' uninterrupted by any furniture
>ceiling fan is out of reach in the living room, but I frequently stick my fingers into it on accident when changing clothes in my bedroom
>bedroom wouldn't really offer significantly more privacy than my living room would, if I'm talking the walls are thin enough my roommates can hear anyway
>living room would require some kind of extension cable or moving my PC, unlike my bedroom
>having VR in my bedroom might motivate me to actually keep my room clean, I have no such issues keeping the living room tidy
>can lay in bed and watch things on big VR tv in my bedroom, but I also have a couch in the living room obviously

Is 5'x9' enough space for room scale? 
Would it be worth upgrading to 9'x12'?
Are there extension cables that work well with an Index?
