We booked a fancy shmancy air conditioned (if necessary) apartment for September facing rue St. Antoine across from the St. Paul Metro because that was what was available at a late date. (We wanted to be in the 5th, 6th, or 7th, but there was no availability) The agency just alerted me that they have a smaller place with plusses and minuses (plusses: quieter street and 1000E less; minuses: 4th floor walkup, no AC if there's another horrible heat wave) and farther from some friends across the river.) I know rue St. Antoine is a tourist-mobbed location but I figured we could easily walk to quieter areas in the Marais. Does anyone know what the rue de Poitou area of the Marais is like in terms of cafés, boulangerie, grocery stores, general feeling? Merci.
