I visited this port and the city on a cruise in the Mediterranean, took an excursion and then wandered around the city with pleasure, the main thing is not to look at the sights and catch the liner on time)
A very picturesque city in a mountainous area. Beautiful architecture, cathedrals. An interesting museum (but with a Russian-speaking guide). There is a botanical garden (I was not there, because I found out about its existence too late). 2-3 days is enough.
