We stayed at Marc's place for a week and loved it! It's an adorable apartment, and was like a home for us during our stay. We really liked the space, having the two levels, the small lane behind the gate that let to the apartment (which made it feel ultra private), how close it was to the metro (Nation) and vélib' stations, and how comfortable it was. It's also close to Gare de Lyon (about 20 minutes by foot or 4 minutes by RER). We miss it already!
