Anna's place on the left bank is wonderful! Our family of 6 (3 active boys, and a baby) stayed there for 3 months from July to October. It's location is at the center of everything; within a 30 minute walk, you to can get to nearly every major attraction.
Major grocery store at the end of the block, park entrance across the street, Bon Marche shopping a few blocks away, and great restaurants in every direction. You don't have to go far to get what you need.
Anna was always attentive and helped when we had questions, had to adjust our plans, and worked through small issues. As a host see was absolutely great!
