Mar-Mar offers dormitory-style accomodations for students & budget travelers. The dorms are co-ed (mixed sexes) and vary in their offerings (most have kitchens & a few have terraces to sit out on). Mar-Mar also offers private accomodations (rooms & apartments), so make sure to specify what you are interested in when you contact them.
Mar-Mar has no curfew & no lock-out period during the day. Each guest is given a key to their room & it is theirs to keep until check-out. Although there are no safes in the dorms, the office will keep any valuables that you might have in the office for you.
Mar-Mar has multiple dormitory rooms & apartments located throughout the historic hamlet of Riomaggiore. They have a large, 10 bed multi-room apartment (which tends to be a very social atmosphere & a great place for those looking to make new friends) as well as smaller (and usually more tranquil) dorms with 4 beds.
Mar-Mar has an English speaking staff & takes advance reservations. They do require that all guests check-in no later than 5pm on their day of arrival, so don't plan on showing up late at night!
This area is one of the most beautiful in Italy, so don't miss it while traveling this incredible country!
