Don't use this service, unless you want to have a really bad experience and a high risk of having the worst holidays of your life. We hired them for a 5 day trip for 30 people, planned 6 months in advance. One day earlier, they canceled the entire thing because some of the crew members got Covid, not giving us any option (and having paid the full amount already.) They paid us a very crappy hostel and actually, charged us for it 30 Eur each. Then, nothing. We had to re-plan our holidays ourselves because they didn't give us any other choice. Now that I read the bad reviews here, I think they did us a huge favor canceling that boat.
