I've spent quite a bit of time in Sibiu, but it's in the now too-distant past. In the 1970s and 80s, a quick rail trip to Sibiel was interesting for its
church/museum. I mention this mainly because it seems to have changed less than everything else I remember. Hopefully, the beautiful, windy, hilly streets of Sibiu have been preserved, even after the Iron Curtain passed into history.
