1 Zyrha34 cancellation of booking my client book 2 units but its just 1 property . how can i cancel their booking. 8 Aaltje B. You can write to them that she made a mistake and that you like to see one unit cancelled.She can still cancel though. What she has to pay is depending on the cancellation policy of that host. Every situation / host is different. It could be that your client has to still pay a certain amount, because she cancels. Also depending if paid everything before staying or not since that is not clear from your question. Hope this helps. Greetings Aaltje B.
