To get at the Villa I recommend you to take a high-speed train (Italo or Trenitalia) to Salerno Train Station. From there, from April to October, you can take the FERRY from Salerno Concordia to Amalfi (Travelmar), 8 minutes walking.
This will allow you to avoid traffic and enjoy the beauty of the Amalfi coast from the sea.
If the ferries are not available it is possible to take a transfer (book in advance to save money, we can help you to book it) or the BUS.
Once in Amalfi take the bus for Pogerola and stop at the Chiesa di Pastena. Buy more than 2 ticket because only in the Tabacchi in Amalfi you can buy the tickets
From the airport we suggest to book in advance a transfer to save money, we can help you to book it. Otherwise there is the Pintorbus Shuttle from April to October.
Check the route Naples- via papa Leone X, from that stop you can take the bus and drop off at the Church of Pastena.
Let us know where you are leaving from so we can give you the best directions to reach Amalfi and Villa Hotel Cappuccini Convento in the simplest way.
