We had a wonderful four night stay in this apartment. The space itself is perfect for two (plus our two month old baby) and is simply but comfortably furnished. The living room has great views out over rue Saint Antoine and the Parisian apartments facing it, and the open plan kitchen area is very sociable.
The best part apart the accommodation is its location - right in Le Marais and two steps from Place des Vosges and many of the best streets/ shops/ museums.
