Hi, I’d like to make this room feel a bit more cozy/homely sort of like the ikea adverts; Scandinavian with a ‘I could get cozy here and fall asleep’ feeling. I would really appreciate some advice on something I could easily (and relatively cheaply) do, such a painting/wallpapering a wall or adding a new blanket, curtains or something… annoyingly the grey steps have to stay for said perched dog 
Thank you for any advice
