permalinks - Enabling hierarchical in a Custom Post Type gives error 404

For a project I have a custom post type called Place. This custom post type can have a page as a parent, and that page can have other parent and so on. Place is always at the end of the sequence. At first I created this CPT as non hierarchical, but now I have been asked to reflect the page structure in the URLs (I created a custom metabox to select a page id in the post_parent field).

So I changed my CPT definition to enable the hierarchical setting and the URLs look as expected: /

Where "place-grandparent" and "place-parent" are page slugs. But my problem is that I follow that URL and it gives me error 404. I'm not sure if it is because the parent is of a different type or something else. But that would be weird considering that the URL looks good.

Here is my CPT definition:

function create_posttype() {
    register_post_type(
      'place',
      array(
        'labels' => array(
          'name' => __( 'Places' ),
          'singular_name' => __( 'Place' )
        ),
        'public' => true,
        'has_archive' => true,
        'rewrite' => array(
          'slug' => 'place'
        ),
        'hierarchical' => true,
        'supports' => array(
          'title',
          'editor',
          // 'page-attributes',
          'custom-fields'
        ),
        'menu_icon' => 'dashicons-location-alt',
        'query_var' => true
      )
    );
}
add_action( 'init', 'create_posttype' );

What can I do to make this structure work? The place needs to have a page as parent, because the pages have widgets that show all the children Places.

Also, can I remove the "place" part at the beggining of the URL and still make it work?

I'm a newbie with Wordpress so any help would be much appreciated.
