I traveled three times to Austria - 2011, 2012 and 2019. It was mostly Vienna - first time took a tram to a nearby town - just to get out of Vienna. Second time, got an opportunity to take a tour of the old castle in Laxenburg, where IIASA is housed. Also got to attend the grandeur Vienna symphony orchestra. Another notable attraction was Mozart House. Loved walking around the St. Stephen church area, each time. Third time, I went after 7 years and it was just a revisit of old places in Vienna.
