We have been hosting 2 rooms in our house for about 18 months with an occupancy level of around 70%.
We have been married for 43 years. Now that we are hosting, our opportunities to bicker have been significantly reduced to about 30% of the time.
Not only that, we seem to have got out of the habit even when there are no guests in house. Definitely an undocumented feature of AirBnB.
