Suzanne was extremely knowledgeable and enthusiastic about Viennese architecture. We learned a lot from her, and it has formed the core of my understanding of Vienna circa 1900, the Secession, and how those themes live on to this day. She tailored the tour to our needs as we were the only clients. We took the U4 train line to save on walking and warm up between discussions. We had a day pass so it worked well.
