The need to redecorate, and the fact it's wallpapered so it can't just be given a quick coat of paint.
It also looks a bit dark in the pictures - I don't think the dark wood furniture is doing it any favours there. Getting rid of some of the pictures, ornaments and occasional-table type things might contribute to a more airy, spacious appearance.
I can't see any signs of a bath - just the walk-in shower - that would put me offpersonally, but probably not much you can do about that.
On the plus side it looks well kept and a good size, and nice external appearance too.
