I've been using my Chinese language skills and found a Chinese language classifieds site (netbirds.com), where the above wechat and a dozen or so more are listed, mostly with no pictures, all in Chinese.
The above account says specifically says their services are aimed at Chinese guys looking for a taste of home. Luckily I am of Chinese blood and can just about hold a basic conversation in Chinese so I booked myself in for this afternoon.
Will report back later, hopefully with a smile on my face.
Edit: it does look like most of the classifieds in that site go through to agents each with a couple apartments each with a couple girls. All look like mainland Chinese students. Living the dream.
