1Justified refund (full or partial)
Hi {{guest_name}}, I read this and understand the frustration. {{acknowledged_situation}} is effectively what you describe and I take responsibility.
I offer: refund of €{{refund_amount}} ({{percentage}}% of night/stay corresponding to the inconvenience). Does that seem fair?
Procedure: I go through Airbnb resolution center, you'll receive confirmation email from Airbnb and the refund credited to your payment method within 5-7 business days.
Other things I want to clarify: {{additional_clarification}}.
Really sorry for the inconvenience, and thanks for flagging it constructively.
