Alterations to reservations can only be made directly in your Airbnb account. Airbnb reservations that were below the 30-day monthly discount threshold and were extended to at least 30 days, will receive the monthly discount retroactively. Follow the instructions below to change a reservation in Airbnb.
If you are moving an Airbnb reservation from one sub-unit within a multi-unit to a different sub-unit in the same multi-unit, be sure to check that the dates are available. If you alter a reservation via Airbnb and the sub-unit is unavailable, the reservation will be automatically unassigned from the original sub-unit and moved to the multi-unit for reassignment.
