I don’t quite know what the vcard syntax is, but you cn find that somewhere else.
Looking at your code, I would do it as follows:
$field = get_field_object("location");
echo "<h5>" . $field['label'] . "</h5>";
$post_object = get_field('location');
if ( $post_object ) :
?>
<p><?php the_field('street_address', $post_object->ID); ?><br>
<?php the_field('suite_office', $post_object->ID); ?><br>
<?php the_field('city', $post_object->ID); ?>, <?php the_field('state', $post_object->ID); ?><?php the_field('zip_code', $post_object->ID); ?>
