Jay's place was fantastic. First, the location was great; not far from any sites but far enough that it's quiet and more true to living with the French. It's a short walk to several metro stops and really is only 30 mins or less to anywhere worth seeing (which includes walking to stop and the metro ride). Jay also provided lots of little extras; a welcome gift, new coffee, extra towels, made sure there was laundry detergent, and more. He made some excellent suggestions for restaurants and general tips and tricks. Many European bathrooms are quite small and for once my 6'4'' 220 lbs fiancée did not feel like he was too big, he was actually able to shower comfortably here. We would highly recommend visiting Montmartre and staying at Jay's place.
Side note, highly recommend New Europe walking tours whether it's the free tour, montmartre tour or the Latin Quarter.
