Like most others - the garden! Because it's paved, it almost looks smaller. I would probably be reluctant to go see it because if that.
I'd be put off by the bathroom, too, but not as much as the garden.
Agree that photo 10 doesn't look great with the sofa, or the thick rug. Makes it look small.
But the rest of your house is lovely!
I don't know the area though. Is it priced well?
I found the floor plans confusing - no measurements, no garden on it telling me which direction it faced, etc.
