We had a good stay in Xavier's very spacious apartment. The location is perfect, and it was comfortable for the three of us. A few concerns: the steps down to the bedrooms and bathroom are narrow and winding and not good for people with mobility issues (but the shower area is very cool/attractive, and we slept well); wifi didn't work for a couple days. He eventually resolved the problem and was easy to reach and communicate with (and there is public wifi in all Paris parks ), but this was an inconvenience; there were a couple electrical issues; lastly, we chose Xavier's apartment in large part because it looked as if he lives there, and we hope that's the case. He has another apartment for rent below this loft. My French boyfriend and I are very concerned about preserving the fiber of Parisian neighborhoods - so they're not made up of a constant stream of tourists, but instead of the people who live and work here most of the year. That's what AirBnB should be about.
