When I first started with Airbnb, in 2016, I had a two night minimum and after that first year I wonder why I wasn't getting the bookings I expected. So, I went with the one night option and bookings picked up... The area in which you live might play a role in the number of nights people want to stay. In my case, people are usually traveling through. Since I do all my own cleaning, I decided to keep the night before a reservation and the night after a reservation blocked, so I'm not killing myself trying to keep up with changing bedding every day of the week. But, what works for me may not work for you. Good Luck and hope you find a happy medium and one that works for you.
