I stayed in Wolfgang's home for two nights. The first night I arrived at almost 2 am because of a train delay, and he stayed up to wait for me. I thought that was so kind, especially because he definitely did not have to. His place was clean, cute, and in a great location. Prater park is walking distance, which was my favorite part. Wolfgang has a great Airbnb and is an equally good Airbnb host. Highly recommend!
