You can continue to use your bungalow or chalet as much as possible. However, you must block the agenda in time via the owners login.

This is how your own use is described in the agreement.   

1.2. Reservations for personal use (including by parents-in-law and persons belonging to the Owner's family) are also possible during the calendar year if the Rental Property has not yet been rented. Bookings must be made exclusively via the owner login.
