The apt worked out well for us (parents with one teen): good sleeping arrangements, functional kitchen, good shower, excellent location for the various directions we needed to go for a week in Paris (and small supermarket right downstairs). Since there’s no air conditioning (and just one mediocre fan), think hard if there’s a chance it will be hot. When we departed one of us (ahem, not me) left her phone in the apt — Arnaud replied to my message very quickly, sent someone to find it, and they DHL’d it (not for free, of course) to our next stop in Alsace. Very appreciative.
