Try the code below. I hardcoded the "About me" to avoid you to use a localization plugin.
/* COMPANY ADDRESS */
if( !empty($zerif_address) ):
echo '<div class="'.$footer_class.' company-details">';
echo '<div class="icon-top red-text">';
if( !empty($zerif_address_icon) ) ?>
<a href="<?php echo get_permalink( pll_get_post(722) ); ?>"><?php
if ( 'en_US' == get_locale() )
echo 'About me';
else
echo 'About me in Finnish'; ?>
</a> <?php
echo '</div>';
echo $zerif_address;
echo '</div>';
endif;
