Difference between "all the time" "occasionally" available accommodation

When you create your ad, available for residences with services only,  it is asked to indicate if your accommodation is available "all the time" or "occasionally".

An accommodation available "all the time" means that you only have to fill in the periods of unavailability. Your accommodation will therefore be available outside these periods.

An accommodation available "occasionally" means that you only have to fill in the periods of availability. Your accommodation will therefore be unavailable outside these periods.
