Have you ACCEPTED the reservation request?
I realise if you don't you risk a bad review.
I did soemthing along similar lines recenlty - a 2 night stay, for 2, wanted to bring their 2 sons wanting separate rooms for 1 night only - meaning I had to make up 2 extra queen beds for only 30pp - not worth my while for a 1 night stay.
so you could reply similarly to me saying, "My booking minimum is 3 nights, - with set up and cleaning I lose money on anything less than a 3 night booking, so it's not financially viable for me.
Since you seem new to the platform and not really aware of protocols and proceedures, I'll be accommodating this once. IJ ust to let you know though xxx that most hosts would really mark you down on stars for an last minute alteration request that violates their terms and conditions. This would make it difficult for you to book quality accommodation in the future as good hosts always check their guests ratings"
- you now have the upper hand - ( if not the money you should have) you've let him know he was out of order, you come across as incredibly understanding and generous and you've subtly let him know that there are repercussions for this sort of high handed behaviour - he doesn't hold all the power.
might not help, certainly can't hurt
