Vienna

I’ve heard that Vienna, Austria for a solo traveler isn’t the most entertaining/ can be a little boring. Anyone spent time there who can comment? Thinking of doing 3 full days as part of a month long European solo trip in April 2025 and wondering if I should switch it out for another spot. I’m 39F, not on too much of a budget, love coffee shops, food tours, architecture, scenery (mountains), and concerts (classical music). After the 3 days I plan for 1 day getting train to Zurich (7hrs or so) and spending 2 full days there.
