Being traumatized by seeing a corpse is just an unfortunate construct of most westernized countries, and I'm sure some eastern countries. But a lot of places it is not always traumatizing. I think the suicide angle depending on how it's done can add trauma to it, though. I wouldn't want to do it in anyone's loved property, but most Airbnbs aren't "loved" property. I have always been of the thought I never want to drag anyone into my suicide. Especially someone who works their ass off for nothing at a hotel. I've always been a proponent of scheduled email, but that's what saved/fucked me last time. Not in the sense that the note made someone come and find me, but that I had been found and the note identified the drug in my system, they just thought I had no drugs in my system and it was respiratory failure caused by something else after they tested me for all the usual suspects.
If in a hotel or Airbnb where someone innocent who is not expected to come across a corpse or isn't paid well enough to come across a corpse is present, I've always thought about taping up a sheet in the doorway to whatever room you're in and saying caution dead body call 911, do not enter.
