It's lovely, and the warm, airy pastels make the most out of modest-sized rooms.
The bathroom is quite cold, maybe a house plant on each window sill to warm it up and a warmer colour of towels.
Cleaning the paving, rearrange the play equipment and a few pots will jazz it up.
(Get a large-ish pot, put a feature plant like a small phormium in the middle then surround with crocuses/ snowdrops and winter pansies. Cheap and cheerful way to add interest and colour)
There's no point in redecorating. Everyone has their own taste, and I'd rather start again and replace something that is tired than have to either endure something new that is not my taste or waste something that isn't fundamentally worn out. We bought our house despite the deplorable brown patterned wallpaper- just made it a priority to redo the lounge within months.
It looks pleasantly lived in and neat. I'm suspicious of the show home style which shows no hint of occupancy as it makes it difficult to judge the potential to actually fit in life stuff.
