Thank you very much for your answer Mrs. Clare's answer!
I still have a question: how do you think I should go with the guest who has already book instant in 24.11.2017 from 31.12.2017 to 01.1.2018? I immediately after booking instantly, I responded that it is okay but wait if it will be from 30.12-02.1.2018 I can send it a special offer. But he did not answer for a few days. After 4 days, I send another messaje "Hi, I apologize, but the minimum stay for the New Year's Eve is 3 days. If you want to stay from 30dec.-1ian is ok! If not, Im sorry but I will have to cancel your booking!" That happened on Tuesday 28.11.2017. She did not answer me until today when she wrote: Hi, you can to cancel my booking, I already bought the flight tickets and I will arrive at 31.
That was our whole conversation! 🙂
I have two variants: 1) pays from 30.12.2017 to 01.1.2018 and a case when it comes, that is, at 31 am! or 2) if she do not accept a 3-night option can I cancel her reservation!?
I do not want to ruin our New Year! He still has enough time to reserve elsewhere.
And if there is any violation of the regulation of Airbnb in this case.
Thanke you again!
