@Richard199 You can run an ethernet cable from your router to the AirBnB apartment and add an extender at that point. Rename the network via the extender setup and give it a separate unique password. I have this setup between my house and garage efficiency apartment where I have a long term tenant and it works well. This should ensure your safety and theirs.
I am using a Securifi Almond as it has a touch screen that I can walk a customer through or connects to my Alexa for me to "fix" via my phone. Yes, this unit is an older product, but for my purposes it has been the easiest to use and reset with guests who messed things up as it doesn't require a computer for setup.
