I hate the wallfabric. It's a migraine in pictorial form.
Somebody needs to chuck out 85% of the pointless cushions and put the books away, as they just make it look too busy, bright (as in the colours are shouting at you constantly) and messy. And some of the rugs are bloody awful, cheap and nasty looking (even though they probably cost a fortune) and look like large versions of something from Amazon or Argos.
The shower room would benefit from whitewash.
The kitchen's just a bit Meh. Same as you'll find in any catalogue.
Other than that, the bare bones of the place and the old furniture are nice. I'd fight anybody that wanted to take a paint or varnish brush to old furniture, too, as that shabby shit look is horrendous and wood should be in different colours because trees are different colours.
I'd add more white, more green, especially in the form of plants and flowers, more wood rather than brightly coloured furnishings on new brightly coloured furniture and want it to look more like a calm, peaceful, relaxing place that is 'old', rather than try to pretend it's a new build or the place where Laura Ashley hide all their bankrupt stock.
