Thank you very much for the helpful and prompt advice.
I’ve written to the guest as follows. The wording could probably be improved, but it doesn’t seem important enough to obsess about. And I hope he doesn’t give me a bad review. If I had to guess, I’d say that he won’t give me a review at all. He doesn’t seem like the most communicative of people - most of what I’ve written to him he hasn’t responded to.
I wasn’t really sure about the offer to make a partial refund (for one thing, I don’t know what would be reasonable, and it’s more annoying stuff to think about), but I suppose it might help placate him, and it’s not a binding legal contract.
And I don’t understand why Airbnb allows guests to make reservation change requests after arrival - it’s rarely a reasonable thing to do. And if the host wants to give money back to the guest, there are other ways to do it. It’s just putting the host on the spot, and making him/her look like a bad guy.
And I see I have a typo - I’m should be I’ll. But Airbnb doesn’t allow edits to messages.
Forum members, please do feel free to critique my message (and others past and future). I’m always willing to learn and improve.
I don’t accept requests for reservation alterations after commencement of the stay - this is not what reservation alterations are meant for.
The usual/standard thing is to cancel your reservation for the days you don’t want to stay. You will get a partial refund for the days you are not staying, per my cancellation policy, which is moderate. See the cancellation policies here - https://www.airbnb.co.in/home/cancellation_policies
It is unlikely I will get a new reservation for the period that was blocked by your reservation (24th March to 29th March), but if I do, I’m consider a further partial repayment for the booked days, if any.
