How to hide Comments for some page?

To hide comments on a specific page, follow ‘WP-admin -> Pages’ and click the ‘Quick edit’ link. You will see the ‘Allow Comments’ checkbox.

You are able to do the same via Adding/Editing interface. Simply check the ‘Discussion’ checkbox in Screen Option (right upper corner). The appropriate box will appear.
