Agnes and Pierre's flat is a little slice of heaven in La Marais. Small, but fine for a couple. Very charming in the back of a little courtyard off a pretty street. A boulangerie, Tout Autour du Pain, is just up the street to the right as you leave the flat, and and there are several cafes out the door to the left. (We loved the manager and waiters at the local spot Le Bistrot, at the corner of intersecting streets and a center of celebration the night of the World Cup win!)
Pierre was a highly responsive host and very generous. We'd highly recommend his flat as a base for exploring La Marais and the rest of Paris. (Musee Picasso is an easy walk away!)
