I wanted to ask if on the mobile theme veronika

Yes you can, modify these two files

1-   in loop-single.php

Add this code

<div>
       <span class="locationcity "><i class="fa fa-map-marker"></i> <?php if ( osc_item_region() && osc_item_city() != null ) { ?><?php echo osc_item_city(); } ?></span>
                  </div>

Under the line

<?php if( osc_price_enabled_at_items() ) { ?>
        <div class="price"><span><?php echo osc_item_formated_price(); ?></span></div>
      <?php } ?>

2- in style.css

Add this style

.locationcity {
    background: #fff;
    color: #444;
    padding: 5px;
    font-weight: 500;
    float: left;
    width: 100%;
    font-size: 13px;
    overflow: hidden;
    text-overflow: ellipsis;
    white-space: nowrap;
    display: block;
}

and you are done

Thanks. I also add this feature
