There are a few similar websites to Airbnb that do not require hosts to provide accommodation in their home. One example is Couchsurfing, which allows people to stay in homes, apartments, and other places that are not their own. Another website that is similar is VRBO, which also allows people to stay in homes, apartments, and other places that are not their own.
One alternative to Airbnb that doesn't require you to provide motel-style accommodations in your home is VRBO (Vacation Rentals By Owner). This website allows homeowners to list their properties, including entire homes, apartments, and vacation homes, for short-term rental. You can list a room, however, it is generally focused on entire home rental.
Another similar site is Booking.com, which offers a wide variety of lodging options, including apartments, vacation homes, and guesthouses, as well as traditional hotels. They also provide the feature of private rooms for rent, however, it's not their primary feature.
Additionally, HomeAway is another alternative, which is similar to VRBO, it operates in the same way and focuses on entire home rental but with a larger inventory and it operates in multiple countries.
It's worth noting that each of these websites have different policies, fees, and regulations that you'll need to review before listing your property. It's advisable to compare the options and choose the one that best fits your needs.
