The layout is a matter for CSS. It looks like this is supposed to be a list of some kind, so mark it up as such with HTML:
<!– Begin Custom Fields –>
<ul class="amenities">
<?php if ( get_field(‘kitchen’ ) ) : ?>
<li><?php the_field(‘kitchen’); ?></li>
<?php endif; ?>
<?php if ( get_field(‘air_conditioning’ ) ) : ?>
<li><?php the_field(‘air_conditioning’); ?></li>
<?php endif; ?>
<?php if ( get_field(‘dishwasher’ ) ) : ?>
<li><?php the_field(‘dishwasher’); ?></li>
<?php endif; ?>
…
…
<?php if ( get_field(‘handicap_friendly’ ) ) : ?>
<li><?php the_field(‘handicap_friendly’); ?></li>
<?php endif; ?>
</ul>
<!– /End Custom Fields –>
… and then use CSS to lay it out the way you like. For a list displayed in multiple columns you can use the columns CSS module.
