@Daniel964, there is a minimum price, you can't rent for 1 $ nor 1$/day.
It's forbidden to get fake guest reviews, as indicated in the review guidelines. Funny, that you announce it on an airbnb forum 😉
So, follow the advice above and ask the family to leave you recommendations. That means: you send them links to join the service. They set up a profile and then write a recommendation. You get a notifications, that it is written. Then you have the choice to accept it or to refuse it, not to edit it (clear it with the writers before they send it).
If later any of your friends travels with the new profile, you both get travel credit.
If you are a new host but have some recommendations from different persons, who know the place, it helps for bookings too.
