You can link your existing personal Airbnb account to your Imperial email address.

Go to your account profile settings when you have logged in to the Airbnb site.  Enter your Imperial email address in the business email address field.  You should then get a verification email through to enable you to use the same profile.

You do not need to create a separate account.  Click on the link from the verification email sent to your Imperial email account but log in with your regular Airbnb details.

Remember to check the the ‘business travel’ check box when finalising your booking.
