Finally, send me a quick message if we should wait for you for the tour on Monday evening (you can contact Paola at 0039 3472703415).To get to the hotel: take a bus from the airport to the station or, better, get off at the Piazza Municipio (Molo Beverello) and from there walk to the hotel (see attached pic).
From the station, every bus goes to the Piazza Municipio.
However, a taxi is easiest.
