It just needs the photos restaging to me. Create the 'ideal life-style' image for the buyers.
Get a table and chairs and nice pots out in the yard- put a little pot of lavender on the table and wine glasses, add nice colourful plants in pots round the edge of the garden.
Take that tablecloth off the dining table and have a lovely full fruit bowl.
There's a lot of stuff in the kitchen, put away the rubber gloves, cloths, washing up liquid, things stacked on the work surfaces, little ornaments etc., and instead put one big green plant in the middle of the windowsill, leaving everything else clear except for toaster and kettle.
The kid's room looks unlived in and stark- looks like it needs more storage for toys- I'd re-arrange it as I don't like furniture and beds all round the edge of a room. It also needs pictures on the walls and a colourful rug.
In the bathroom get rid of the corner unit thing with all those cheap toiletries on and instead add some beautiful glass bottles of bubble bath on the windowsill and posh soap and hand cream dispensers by the sink. Add a big tropical houseplant on the floor in the corner where the toiletries currently are.
The sitting room just needs a nice big plant in the bay window.
