"Our Shower In Croatian Airbnb"
"We stayed at the Airbnb for a few months, and I used this to heat the bathroom. I didn't know if I would get electrocuted or barbecued. It did heat the bathroom pretty well, but it took up so much power in the apartment that you couldn't run anything else simultaneously, or it would trip the breaker."
Exactly my 1st thought.
#12 is a fail by the guest.
#14 is pretty common at hotel pools.
Next time I'm not alone in a room with one of those I'll smear the glass with toothpaste, shampoo or whatever to get some privacy.
