Treehouse has a convenient location in San Marcos, Texas near Texas State University. We have fun community events and four different spacious apartment floor plans to choose from. But don’t take our word for it. Take a look for yourself. A picture is worth a thousand words, we've been told. But nothing beats the experience of a visit. Stop by Treehosue and take a tour. We'll show you why Treehouse is clearly the best choice for off campus housing.
