Bay Area woman says guest shot porn at her home

We suspect that this happened in one of our listings, a few years ago.   After the booking was confirmed and I had the guest full name I did some cyberstalking and saw that she had a number of suggestive photos online.   Seeing that give me a bit of a worry, but then I thought about my own niece who has racy photos online too, and she's quite normal.  Anyhow the guest was completely non-communicative during the stay, not responding to texts, emails or phone calls and I was just wanting to make sure everything was going well.  After two days I drove by, let myself into the gated yard and knocked on the door - no answer.   I peered through the curtain and the place wasn't on fire and while the kitchen was messy it wasn't a big thing.  I couldn't see very well.

They finally check out and we go to clean, and all the furniture had been moved.  Everything had been unplugged, and lights/lamps all in the master bedroom.   There was lots of indications that something had gone on, and my husband, who has film experience said - they shot a film in here.    Then we find the bathroom bins filled with condoms, lube packets, twist ties, the paper ties for extension cords, the tub is filled with makeup stained towels - like stage makeup, not normal mascara.   

I bet it happens a lot.   NYU film students at least ask if they can film before they book!
