@Naziha5 There are variables on cancelation policies. Best way to find out is to click cancel reservation and it will tell you what you are committed to. It’s likely 30 days but only you will know.
You can ask your host if they will refund you. Do this through AIRBNB messaging. It’s up to you whether you trust them to refund.
If you are still paying for 30 days, do not cancel!!! You will be paying for 30 days more but out on the street and then having to pay for a second place at the same time if your host isn’t willing to refund you.
Instead, you can change your reservation to the minimum number of days, find another place for at the end of your 30 day stay. Make tons of inquiries about sound proofing with the new place. Meanwhile, invest in some really good earplugs, white noise machine and do your best. Good luck!!
