schema.org markup and nesting for Review of "ApartmentComplex" - schema.org

Question

I have some structured data implemented in my website using microdata so that Google and other search engines could parse it and show appropriate rich snippets. I have added the appropriate markup for all the microdata tags that I have used but I am unable to view the rich snippets for my website while testing it using the Rich Snippets Testing Tool. I have gone through the usage guidelines and frequent issues section at the Google Webmaster but to no avail.
Upon debugging the html I found that the following snippet was successfully showing rich snippets when fed to the Rich Snippets Testing Tool.
<div class="row">
<div class="col-sm-12">
<div class="page-header">
<h1><span itemprop="name">T Park </span></h1>
<div itemprop="address" itemscope itemtype="http://schema.org/PostalAddress" class="address">
<span itemprop="streetAddress">1 Scenic Park</span>
<span itemprop="postalCode" class="hidden">123456</span>
<span itemprop="addressRegion" class="hidden">Central </span>
<span itemprop="addressCountry" class="hidden">Singapore</span>
</div>
</div>
</div>
</div>
<div class="col-sm-6 box-map">
<h2>Location</h2>
</div>
<div style="margin-bottom:0px;" itemprop="review" itemscope itemtype="http://schema.org/Review" class="jumbotron row">
<h2>T Park Reviews</h2>
<br>
<meta itemprop="itemReviewed" content="T Park">
<div id="reviews" itemprop="reviewRating" itemscope itemtype="http://schema.org/Rating">
<meta itemprop="worstRating" content="1">
<meta itemprop="ratingValue" content="9">
<meta itemprop="bestRating" content="10"><span>Rating: 9/10</span>
</div>
<br><span itemprop="reviewBody">Lorem Ipsum....</span>
<br><strong itemprop="author" class="row pull-right">John May</strong>
</div>
However as soon as an enclosing markup of ApartmentComplex is added as shown in the snippet below, the rich snippet is not visible.
<div itemscope itemtype="http://schema.org/ApartmentComplex" class="container">
<div class="row">
<div class="col-sm-12">
<div class="page-header">
<h1><span itemprop="name">T Park </span></h1>
<div itemprop="address" itemscope itemtype="http://schema.org/PostalAddress" class="address">
<span itemprop="streetAddress">1 Scenic Park</span>
<span itemprop="postalCode" class="hidden">123456</span>
<span itemprop="addressRegion" class="hidden">Central</span>
<span itemprop="addressCountry" class="hidden">Singapore</span>
</div>
</div>
</div>
</div>
<div style="margin-bottom:0px;" itemprop="review" itemscope itemtype="http://schema.org/Review" class="jumbotron row">
<h2>T Park Reviews</h2>
<br>
<meta itemprop="itemReviewed" content="T Park">
<div id="reviews" itemprop="reviewRating" itemscope itemtype="http://schema.org/Rating">
<meta itemprop="worstRating" content="1">
<meta itemprop="ratingValue" content="9">
<meta itemprop="bestRating" content="10"><span>Rating: 9/10</span>
</div>
<br><span itemprop="reviewBody">Lorem Ipsum....</span>
<br><strong itemprop="author" class="row pull-right">John May</strong>
</div>
</div>
So assuming my page is about ApartmentComplex, and I want to include a Review of it, how should I structure/nest this markup?

Answer 1

I don't think there's anything wrong with your mark-up or Microdata. I just don't think that the Google Structured Data tool shows any rich snippets for http://schema.org/ApartmentComplex types - rich snippets are only available for certain schema.org types.
To prove this, change the wrapping ApartmentComplex type to a Product type, and remove the address (which isn't part of "Product") and you'll see that a rich snippet is produced in the Google Structured Data Testing Tool (because Google do show rich snippets for Products).
Edit to add: this is a possible workaround - Google will show rich snippets for schema.org types where the surrounding type is a Review, so you could use Review as the top-level type, then have the ApartmentComplex type as the "itemReviewed" property - this works in the Google Structured Data Testing Tool:
<div itemscope itemtype="http://schema.org/Review" class="container">
<div class="row" itemprop="itemReviewed" itemscope itemtype="http://schema.org/ApartmentComplex">
<div class="col-sm-12">
<div class="page-header">
<h1><span itemprop="name">T Park </span></h1>
<div itemprop="address" itemscope itemtype="http://schema.org/PostalAddress" class="address">
<span itemprop="streetAddress">1 Scenic Park</span>
<span itemprop="postalCode" class="hidden">123456</span>
<span itemprop="addressRegion" class="hidden">Central</span>
<span itemprop="addressCountry" class="hidden">Singapore</span>
</div>
</div>
</div>
</div>
<div style="margin-bottom:0px;" class="jumbotron row">
<h2>T Park Reviews</h2>
<br>
<div id="reviews" itemprop="reviewRating" itemscope itemtype="http://schema.org/Rating">
<meta itemprop="worstRating" content="1">
<meta itemprop="ratingValue" content="9">
<meta itemprop="bestRating" content="10"><span>Rating: 9/10</span>
</div>
<br><span itemprop="reviewBody">Lorem Ipsum....</span>
<br><strong itemprop="author" class="row pull-right">John May</strong>
