The host was most welcoming and helpful. What impressed me most was that we had some problems with getting the hot water turned on when we arrived. We notified the host by email. They responded immediately and walked us through a process to reset the thermostat which resolved the problem immediately.
The flat was accurately depicted in the pictures on the website. It was located in what seemed to us like a typical working class neighborhood. Many bakeries, markets and butcher shops were within walking distance. A metro stop is immediately outside the building entrance. The neighborhood was busy with pedestrian traffic but not touristy (we saw very few people in the neighborhood that we could immediately identify as typical tourists).
I did a lot of research on AirBNB before renting the Wise flat. I think the value (what we got for what we spent was great). I would recommend the property to my friends and what's more, when I return to Paris I try to book the property again.
