Susanne B's charming Paris apartment, good location & good wifi, what more can you ask for?
Helmut Newton at The Grand Palais. Small but worth it. Epic queues.
Hippie Market(21 rue du Temple)in Le Marais, one of the better curated vintage shops in the area. This means everything was laid out nicely and you get to say hey to these two pals. But wander across the road to the less tidy shop and rummage for a couple of hours you may come away with 2 leather jackets, 4 silk scarves and a terry toweling dress for about £30.
A walk through Père Lachaise Cemetery on a rainy afternoon makes for good relaxation time.
Laduree(21 rue Bonaparte)for mid afternoon snack and a proper cuppa.
