Not a fan of the grey wood floor, but otherwise it's beautifully done. My terrace is also done out in a lot of grey, its bright but warmer and less clinical than white. Its clearly been done up to flip so they have kept in neutral.
I know the area and it's priced at the top end of the market so not a huge amount of manoeuvre for making a profit but you wouldn't lose money on it. And as others have mentioned, for £20 you could easily add your own accent colour
