The boat was nice as well as Olaf. I organised a surprise birthday we for my boyfriend and Olaf and his wife helped us! A bit far from the city center but that's the price to pay when you are a big group. It was warm enough, and the bedding was ok. We had some trouble with the beer tap, there was no gas anymore, which could have been noticed earlier. That was the only annoying thing, anything else was fine. And we made some noise during the evening/night without any trouble. I would recommend Olaf's boat if you are a big group !
