@Jennifer1570 Another couple of things to consider: Not sure if you are accepting children and/or pets or not at your place, but be aware that 'Infants' must be accepted (for free) at all Airbnb listings, even if you have checked off that your rental is not suitable for children. Also, service and 'emotional support' animals also must be accepted (for free). And the guest does not need to inform you they are bringing said infant or said service or support animal (although there is an 'infant' box that can be checked off when the booking is made - but some guests do not bother to do this, nor do they bother to inform the host they are bringing their little one - There is no box for checking off service or emotional support animal, either, last time I checked).
Now, a host's idea of what an 'infant' might be (unable to crawl; still sleeps in a basinette; still nursing; still wears teeny-tiny baby clothes; pre-verbal, etc) may be very different from a guest's idea of an infant - especially if said guest is wanting to save a little money (because infant's get to stay for free). The same is true for service animals and 'emotional support' animals. You have to accept them, or you are in violation of Airbnb's (very questionable and controversial) anti-discrimination policy.
So, you might find that that nice couple who booked your place awhile back shows up on their arrival date with a two year old with them (staying for free on your dime) who they insist is still an 'infant'. Or, your guest might show up with a service dog or mini-horse, or an emotional support animal of some kind (dog, cat, chicken, goat, peacock, etc). You then have to decide if you will host them or try and have Airbnb cancel the reservation, which is unlikely to happen, as it will be seen by Airbnb as discrimination on your part.
Given the above two possible scenarios (and you are likely to face one or both if you host long enough) it is therefore best to ensure your place is as child-proof and animal-proof as possible, (including the radiator) so as to limit any liability issues you might face were you to not do so. And do be aware that you really can't count on Airbnb's Host Protection Guarantee (just do a search on the HPG here in the forums and you'll see why). Therefore, in addition to child and animal proofing your rental, you will likely want to look into acquiring some sort of short term rental insurance coverage to protect yourself and your assets while renting out your home to strangers.
