Hello @Tavia0
Welcome to CC.
Have you reached out to Customer Services Team and discussed it with them to see what your options are?
There phone numbers are scattered throughout the CC.
It's always the best thing to contact them first, whatever you do don't cancel the booking yourself, as I understand it may impact on your chances of becoming a SuperHost and retaining your Superhost status ask the Guest to cancel.
If you use related keywords here in CC search box you will also find helpful information.
The last thing you need is to not have any incoming bookings.
If you do agree to the guest cancelling may I suggest you mention that you will be disadvantaged as your place isn't currently able to be booked with the Guest staying.
Maybe you need to sit down over a cuppa with your guest & talk things through re noise if its only temporary or worse at certain times of the day.
All the best
