title: Drupal join on taxonomy terms
body: <p>I have a Drupal setup like this:</p>
  
  <ul>
  <li>Content type: <strong>Apartments</strong></li>
  <li>Vocabulary: <strong>Areas</strong>, that can be used with Apartments.</li>
  <li>Content type: <strong>User profile</strong>, with a Content Taxonomy Field for Areas so users can select what areas they are interested in.</li>
  </ul>
  
  <p>I would like a view that shows all the user profiles that matches the apartments in their area. A "User profile &lt;-> Areas &lt;-> Apartments" join in other words. I've been mucking around with the views interface for a while but it's not clear to me how the relations can be setup to achieve this. Can someone give me a hint?</p>
  
  <p>In case this cannot be easily solved with views, what is a good way of doing it otherwise? Thanks for your help.</p>
