I discounted B immediately because parking seemed to be an issue and the street looked quite closed in/narrow.
I like the fact that C has a toilet upstairs, and the outside space looks more usable than A’s. I also like the fact that in C the stairs don’t come out of the living room.
Without knowing anything more about the area, I’d go with C. But if C is yours (I haven’t read the thread, to avoid spoilers), I would de-clutter and Take some fresher looking photos.
