This £1.2m house in Leytonstone is for sale. Looks normal enough but inside there’s a “murder room”

So this “6 bed semi-detached house” has come up for sale on Zoopla. £1.2m because insane London house prices, but that’s not the story, the story is this room:
JESUS WEPT!
As @cecilyhania on Twitter says, “ideal for any slumlord / serial killer. quick purchase. cash only buyers.”
And as Zoopla says, “this property is sure to attract a lot of attention so book now to avoid disappointment.”
