The conference site is the Hotel Cappuccini (Ph. +39-89-871877, Fax +39-89-871886). From the street (Via Annunziatella 46), take an ancient elevator up to the lobby of this 12th-century monastery. Despite the antique furniture and carpets, you will have no trouble picturing the austere convent this used to be.
To get the above fare, mention that you are a SCN conference participant. Additional hotels are listed here and here.
The Hotel Cappuccini is the building number 12 located on the left of this map. It is on the coastal road leading to Positano and it is not far from both bus and ferry stop (~ 400 m). It has also a private beach and a small parking lot.
