I've lived at Hampton Greens for two years. It's definitely not a "luxury" apartment community, but it's a decent place to live. Noise is usually not a problem, and the maintenance is alright (if a little slow).
So, if you're looking for high-class living; it's not the place for you. But, if you want a decent place to live with access to the 635, it's an okay place.
I'd stay, but I want to be closer to the 75 for work.
