I lived through the seventies.
that stuff wasn't hip then and it's just hideous now.
there is a reason the seventies are known as the decade that taste forgot.
Definitely authentic and/or old lady - those rugs hanging on the walls, the "system" shelfing with ugly tracks, the lack of underlay in the bedroom carpet and the vile curtains are all a dead giveaway. As are the flat as a pancake cushions and the tartan travel rug on the arm of the sofa. The tiny tvs just confirm it. I suspect the bedding comprises bri-nylon sheets and gives off electric shocks.
This place wouldn't look out of place as a set on Sale of the Century.
