Had a perfect stay on the boat with Lore and Xavier. Lovely people with lots of knowledge about the city, spots to eat or drink, places to visit, etc. They're very helpful if you need anything.
Just remember, you're on a boat, so everything is smaller than you're used to. So if you're much taller than 1,80m I probably wouldn't recommend it for more than a few days or if you like hitting your head.
