Location, Location, Location!
Within 2 minutes walk you have a Metro, a chemist, a supermarket, the Seine, a bus stop, a cash point, a Patiserie with pain aux raisins to die for, 2 museums one of which is the amazing Museum of Modern Art, at least 6 resturants all more Parisian than touristic a fabulous street market and lots more I'm sure.
And as for the studio it's clean, quiet, a reasonable size for central Paris and has all the essentials including a Nespesso. All in all a super choice for a short break base in Paris.
