@Karina-and-Craig0 If Airbnb is your primary source of income, and your first priority is maximizing your occupancy rate, you'll probably need some 2-night bookings to fill out your calendar, especially for those tricky weekdays.
If hosting is more supplemental income, and your goal is to increase the quality of guests and the return you get on your investment of changeover time/labor, a 3 night minimum does help here. (On guest "quality": nothing wrong with people making short weekend trips, but when your listing is at risk of attracting parties or other unauthorized uses, that minimum works as a filter).
