If ZUZU created this Booking.com listing for you, you should have received an invitation email to create an account.
This is an example of what the email looks like:
Create a new account by filling in the required information on the form. During this step, you will receive an automatically- generated Login Name by Booking.com. You should store this Login Name safely as you will always need this for all future logins to the extranet.
After the account is created, you are required to log in to make sure it is accessible.
