looked a little too clean
I doubt anyone has said that about this place in a LONG time!
But I see your point, not much junk left around. The walls look to be in good shape, this would be an interesting place to see a full renovation done. Bet it would look great after being cleaned up and repaired.
I did see some reports from years ago and it contained books, magazines etc.., over time they always somehow disappear. I don't know why people would take such things, they tend to be musty, wet and unpleasant.
Maybe they are just voracious readers! 😆
