Okay, stay here at your own risk. I found a small bug on the sheet on the final night of my 2-night stay. At the time I didn't realize it was a bed bug and just took a few pictures, flushed it down the sink and went to sleep. A week later, back at home, I discovered 15+ insect bites on my body (confirmed from the internet that they were consistent with bed bug bites). I also looked up photos of bed bugs and the bug I found on the sheet looks 100% just like one. I called a pest inspector to my place right away, assuming the bites were fresh and that I'd brought bed bugs back with me in my luggage. I also quickly informed the host I suspected her place had bed bugs so she could take prompt action, and sent her the pictures of the bug I found on the sheet. She responded very quickly and let me know that she went to the room and checked the bed, and could not find any signs of them. I replied that bed bugs can be hard to find, and a professional inspection can often be needed. She responded that if her place did have them, I surely would have been bitten during my stay..
Fortunately the pest inspector I called found nothing in my place (for now, I guess) after a thorough inspection. I also did more research and discovered that bed bug bites can take up to 14 days to first appear, so it is very likely I was bitten in this room and just didn't get reactions right away.
I just find it very disappointing that the host would not call a professional to inspect the place, in an abundance of caution to protect the safety of her future guests. Bed bugs are a physical, psychological and financial nightmare, I've just discovered. Stay here if you're willing to risk it.
