An indulgent floating option, this converted cargo boat near the up-and-coming cultural quarter sleeps up to five sybarites, and comes with two bathrooms, jacuzzi, state-of-the-art stainless steel kitchen, and decks dedicated to sunbathing and swimming. At night, sleep on (what else?) a waterbed. Overnight stays are possible, but longer ones are more economical. Check the website for last-minute deals.
