I would like to know how to protect my business from reviews that have nothing to do with us. I have received some reviews from people who have not stayed with us at all but have probably been visiting the area where my hotel is situated. For instance some photos are taken from the nearby taverna but have been given the name of my busnessness.

I don't think you can prevent anyone from posting reviews to your GMB listing. What you can do is respond to the review. Here are some tips from Google https://support.google.com/business/answer/3474050?visit_id=1-636270046062478612-1580090809&rd=1 here's an article on how to deal with fake reviews https://whitespark.ca/blog/remove-fake-google-reviews/
Hope it helps =)
