The OP did not start this for people to critique the decor.
Doesn't matter what the OP's intentions were, it's pretty obvious that people are going to comment on the decor (and despite all the indignation at poor photos, posters ARE criticising the house itself).
It isn't up to the EA to clear up the house before photos, they can advise but if the vendors are happy with it being marketed like it is that is up to them. I don't know the Potter's Bar market, maybe that's cheap and anyone with sense will see through the photos and snap up a bargain.
I do wonder why people post threads like this, I'd hate it if houses belonging to my elderly relatives appeared on MN for public scrutiny.
