You have things a bit mixed up here, I don't think that you have a clear vision of what you are building.

<div class="neighborhood-guides">
    <div class="thumbnail">
        <img src="http://goo.gl/an2HXY" >
    </div>

<div class="container">
    <h2>Neighborhood Guides</h2>
    <p>Not sure where to stay? We've created neighborhood guides for cities all around the world.</p>
   </div>
  </div>

<div class="row">
    <div class="col-md-4">
        <div class="thumbnail">
            <img src="http://goo.gl/0sX3jq" >
        </div>
        <div class="thumbnail">
            <img src="http://goo.gl/an2HXY" >
        </div>
    </div>

   <div class="col-md-4">
   </div>
  </div>

In exercise 6, here is the overall plan that you are aiming for in your neighborhood-guides:

<div class="neighborhood-guides">
    <div class="container">
        <h2>Neighborhood Guides</h2>
        <p>Not sure where to stay? We've created neighborhood guides for cities all around the world.</p>

        <div class="row">

            <div class="col-md-4"> <!-- begins 1st column -->
                <div class="thumbnail">
                    ... first thumbnail code here
                </div>
                <div class="thumbnail">
                    ... second thumbnail code here
                </div>
            </div> <!-- closes 1st column -->
			
            <div class="col-md-4">
            </div> <!-- closes 2nd column -->

            <div class="col-md-4">
            </div>  <!-- closes 3rd column -->

        </div> <!-- closes row -->

    </div> <!-- closes container -->
</div> <!-- closes neighborhood-guides -->
