I moved to Austin to go to the University of Texas and loved it so much I stayed! I love the outdoor living in Austin. My place is 5-10 minutes from Lake Austin and downtown. The bike path that goes all the way to Town Lake is right outside my door. Great ride down, though bit of a hill coming home. :)
When you visit Austin, make sure you plan to be outdoors a lot. You can take a cab downtown from my place and walk almost everywhere from there. If you have time for exercise, run around Town Lake or rent a stand up paddleboard from SupATX. It isn't expensive and it's super fun!
Great restaurants, clubs, bars, etc too. Some of my favs in Austin are Mexican - Maudies, Sushi - Uchi, Uchiko, Kenichi, Pizza - Home Slice on South Congress.
