@Nashi4 Some entire home listings are used exclusively for Airbnb, and some are homes where the hosts normally live, or live for part of the year and may have their personal belongings in it. Some hosts may only list their home when they are away travelling themselves, or may just go stay with a relative or friend when they have a booking. Sometimes this is the only way a host like a single mom can afford to keep up her mortgage payments and wouldn't necessarily choose to do this if they weren't in financial straits. Usually those listings make sure to leave adequate closet, drawer, cupboard and fridge space for guests to put their things, at least one would hope they do. There's nothing not legit about listing an entire home as long as the guests have the space exclusively to themselves during their stay. But hosts usually make it clear in the listing description that they live in the home some of the time and that there will be their own stuff there as well- clothing, dishes, stored food or maybe things in the fridge.
If you thoroughly read through all of the listing description and this wasn't indicated anywhere, you might suggest to the host in private feedback that they should change their listing info to make it clear what the situation is.
