Anne-Laure sent a very helpful email explaining how to pick up keys (we never saw her). Very clear directions. Flat VERY quiet, but that is because it's an interior unit facing cement walls. Note there's no real outdoor space, and the entire flat is maybe 300 sq ft. The bathroom is basically a sink, and a shower curtain separating the sink from the toilet and showerhead, so very boat-like. But for a weekend, it's a great location, walking distance to both Gare du Nord & Gare d'Est, and Canal St. Martin.
