Re: Ya' sure it's not the revenge of non-air B&B owners?
And note for your own safety B&B's have to have wired smoke and incident heat alarms, if they have more than X rooms, sprinklers. They must have an annual gas safety inspection. Stuff like that. Your ABnB host? nada. Domestic properties do not encounter gas explosions all that often, but they do happen. Fires happen much more commonly.
Oh yes. Your B&B will have fire extinguishers. I have one, it's tiny and rather old. There's a fire blanket too. The smoke alarms aren't wired so that beeping that wakes you in the night? probably the battery empty signal.
