A really great spot, especially proximity to RER (from airport) and walking distance to so many great places. Just a couple of minor things to be aware of--difficulty with Internet connectivity and noise (apartment is over a bar). The bar noise definitely wasn't terrible--but my earplugs came in helpful. I'm all but certain the Internet will be working for the next person who stays here. And Marjolaine was SO wonderful and responsive and helpful.
All in all, it was a great place to stay. I would stay here again.
