I had 3 bookings cancelled :
1st. cancelled the check in day : the lady did not do her visa and was empeached to take the plane.
2nd. changed their mind 6 months in advance. The place was rebooked a few days later
3rd. The gentleman broke his elbow 1 week before their arrival date.
But the most tricky to manage for me was not strictly speaking a cancellation but a modification without my approval.
I had a booking for many months and i suddenly received a message saying that the dates were changed by the tenant to 1 month.
I discovered that for for lon-term lease (> 28 days), the traveller can change the dates without the approval of the landlord to shorten the rental if the modification is done more than 1 month before the arrival.
I was obliged to change the house rules :
"Long term lease are commited to respect the French Law which requires the tenant to rent for a minimum of 9 months in Paris.
If the guest books for 9 months and then wants to stay for less time, the approval of the Landlord must have been obtained.
The landlord may refuse to shorten the rental period because the rental would become illegal. Therefore, the tenant would be obliged to cancel the reservation on his behalf."
