there is not really alot to see in sibiu but there is! The question is, do u want to the the "classic" traveller side of sibiu (big churches, maybe even Kathedrale the old city center)basiclly the nice side that everyone wants to see when they visit a city, or do u rather wanna explore and also see the small, "not perfect spots" maybe even "the hoods" and stuff like that, or maybe even not actually Sibiu, but the mountains around it. Let me know
