Airbnb's in Italy - smoke detectors

I wouldn't worry. Most likely, these are in stone buildings with meter-thick walls. Fire insurance isn't even a thing in most of Italy, You're going abroad; get used to different standards and cultures. At the same time, food quality and health standards are much higher than in the U.S.

Buy a smoke/carbon monoxide detector when you get to Italy.

Hi em,

Have you already confirmed with the apartment owner that they do not have a smoke or carbon monoxide detectors? Or find one who does. Of course, you can leave some of the windows open.

I never smoked. I stay in hotels and have always had detectors and ceiling sprinklers in the rooms. But I have no idea how some hotels, private apartments, private B&B's, etc. operate by the owners.

Google "travel smoke detectors." It may be worth the extra weight for your peace of mind. Also, it's good to be organized -- A suggestion: Before you go to sleep, put your PP, any money and cards in your purse/bag where it can be grabbed fast in case you need to exit immediately (for any emergency.)

Adding, as someone above suggested, look to buy (a battery operated) one at a hardware (or electronics) store in the neighborhood. If so, make sure you have an accurate translation/description in case of miscommunication.

If I'm not mistaken, it's not a requirement for Italy or Spain to have smoke detectors in residential units. If this is a problem for you then yes, I'd only rent a flat that does have a requirement. Probably better and cheaper than carrying a smoke detector with you.
