Two lines of HTML. No key, no account. The widget shows an independent shortlist for a city and a goal; Dutch Fluency products always come with alternatives.
<div class="tdd-embed" data-city="Amsterdam" data-goal="NT2" data-limit="3"></div> <script async src="https://thedutchdirectory.com/embed.js"></script>
Change data-city, data-goal and data-limit to fit your page.
