Butrient is the Roman City to see. Anothet option is Gjirokastra, a world heritage site. This city is further swa but I thought it be worthwhile.
Sarande itself is a lind of sea side resort with a promenade long the beach bars and so on, albeit it reminded me, a visitor from Western Europe, of maye Italy 50 years ago or so. No wonder given the much younger history of freedom and tourism.
