Eight of us stay for two nights on the boat and had a wonderful time. The hosts were great - super friendly and very accommodating. They greeted us each morning with fresh croissants, fruit, yogurt, and coffee. The boat is about a 20-30 minute walk from the train station and 10 minutes from some nice, reasonably priced restaurants.
Due to our short stay and weather, we were not able to go out on the boat, but that was ok because we still had easy access to Cinque Terre via the train.
We would do this stay again.
