There are many lodging options in Sestri Levante and the immediate area. With the conference scheduled just between Easter and May 1st (a long weekend in Italy), we encourage you to book your accommodation in advance and as early as possible.
Further note that because the area is well served by railway with each village having its own station, you may opt to book accommodation in a neighbouring village along the Ligurian coast within a 10-20 minute radius of Sestri Levante. We suggest looking into: Lavagna (5 mins), Santa Margherita Ligure (15 mins), and Monterosso (20 mins by train).
