I kinda like the crazy bathroom
rest not so much. There was a lady artist/designer I saw on TV that covered pretty much every surface in a riot of colour & pattern, I love bright arty things but I'd need to lay in dark room was just too much.
Can imagine living in grim place with old swirly carpet and what looks like polystyrene tiles on ceilings may bring some desperation for bright, happy colours. It looks like needs total renovation anyway.
