Change Calendar URL for security

[Alan97]

Hi 

I have an issue, I was working with a cleaner, He suddenly decided to not work in this business. I really do not want my guest info being shared with him anymore, I add the URL to my google calendar and from there shared with him. I am trying for days and I have no success to this point! It should be some way! 

I am wondering why Airbnb put number and name accessible through the URL link! They better to work on their platform. 

Anyway, 

I even try to delete the calendar from my Google Calendar but it remains to the other people who you have shared the calendar!! 
The only way would be changing URL from Airbnb!

Please help!!
