Outside of those times when your vacation helps fund a brutal dictatorship, not spending enough time in the museums is the most guilt-inducing part of travel. Ensure your conscience stays clear, at Au Vieux Panier.
Ensconced in the heart of Marseilles (5mins from the town centre, 5mins from the sea), this 17th-century boutique has turned its half-dozen rooms into veritable exhibits by giving an equal number of vaunted French daubers free reign to decorate as they please, thereby enabling guests to "sleep in an artwork", though technically that's an idea Tracey Emin had years ago. Take your pick of temporary abodes including the Panic Room, which graffiti artist Tilt has divided cleanly down the middle, with one half stark white and the other completely covered with spraypaint tags & throw-ups; Purgatory Palace (from design studio Mass Confusion), whose electrifyingly surreal walls flaunt colourful geometric patterns interspersed w/ biblical imagery; and Parisian street artist Philippe Baudelocque's Fusion, populated by stunningly intricate chalk animals -- so even though there's free cable, you'll have to be careful not to rub one out.
Turn yourself into a bronze on the sun-catching roof terrace, or attempt to make new friends in the communal library/living room space. The website also boasts a comprehensive guide to the coolest stuff going on nearby, including DJ-fueled cocktail spot The Lady Black, '50s-style duds merchants Kulte, and street-art gallery Backside -- stroll over, lest you spend your whole vacation on your own, giving you something else to feel guilty about.
