A perfect base to explore Paris, especially the Marais, the islands, the left bank, and beyond Chatelet to the Louvre. Alexandra kindly provided restaurant, bar and even boulangerie/patisserie suggestions but there are so many other good places, too: try Les Enfants Rouges, rue de Beauce (not cheap not not very expensive either), or
Jackpot, rue des Haudriettes (very good value).
The apartment is a stylish and comfortable haven after a day of wandering, to recharge before the evening.
