Find the "Cancel booking" link in the email
In the letter you will find the "Cancellation cost" clause. Be sure to read the cancellation policy. Some accommodation facilities offer free cancellation, while others charge a fee. Next, click on the "Cancel booking" link next to it and you will be directed to your personal account.
In your personal account, click on the "Cancel booking" button
By clicking on the button, a pop-up window will appear with a list of reasons for canceling your reservation. Select your reason and click "Yes, cancel this booking". Next, you will see a message stating the success of the cancellation and the conditions, under which the booking was canceled.
