My wife and I stayed at a duplex owned by Landry Properties (on Hillside in College Station) back around 2007. It was a family-owned business, and the family had built the duplexes themselves. They were always very responsive to our requests, and were very reasonably priced compared to other options. The duplex was spacious and well laid out. I highly recommend Landry.
Curt is the best! Responsive to problems even little ones. He made moving in to our new place absolutely perfect!
