This is for you if you're looking for an offbeat stay. The marina is not noisy and the water is relatively still, so don't worry about seasickness. The boat was quite clean, and comfortable and included everything advertised. It's located in a beautiful part of the city (albeit far from the centre). It has its downsides (expected from a boat) - if you're tall, expect to bump your head.
All in all, I strongly recommend this stay.
