Charming contemporary inn in a historic grove adjacent to famed restaurant in nineteenth century home. Small but well-appointed rooms with nice bathrooms. Casual bar/snack bar on site. Very quiet and comfortable. Just minutes from downtown Austin but seemingly a world away. Other eateries within walking distance.
