How do you get to the centre from the port?
'Arriva' — ar-RI-va. Double 'r' is lightly rolled; stress on the second syllable.
Ask when you have just disembarked and need to reach the city centre. The port is often in an industrial area and requires transport to reach the historic centre.
'Come si arriva' is the impersonal reflexive form of 'arrivare' meaning how does one get to. 'Dal porto' is 'da + il porto' (from the port). 'Al centro' is 'a + il centro' (to the centre). This sentence uses both 'da' (from) and 'a' (to), demonstrating the key prepositions of origin and destination.

Most Italian port cities have ferries docking near the historic centre — Naples, Bari, Genoa, and Ancona all have city-centre ports. However, in some cities the ferry terminal is in an industrial zone (Civitavecchia, Livorno) and requires a shuttle or bus to reach the city.
