 And also check for one-way mirrors with hidden cams. You want to shine your phone's flashlight through them if you can. If one side of the mirror is brightly lit, you have a problem. Next, check the devices connected to the rental's wireless network for anything strange. And if all this is freaking you out, pick up a hidden camera detector on Amazon. They're about 50 bucks. You also want to scan the highest channels on the cable, too. Sometimes you can find cameras there. I know.
