How to link to Entityform submissions page?
Entitform module comes with pre-built Views that list the Submissions. It is called Entityforms (Entityform Submission) and you can access the Page through 

/entityform-submissions/submissions/accommodation_contact/list

or the Table where you can see submissions directly: 

/entityform-submissions/submissions/accommodation_contact/table

Display one of these links in the Block you created for your owners: 

&lt;a class="button" href="/entityform-submissions/submissions/accommodation_contact/table"&gt;View submissions&lt;/a&gt;

These Pages use the access permission View any entityform submission so allow your owners role this.
