This is a fun, interesting apartment in a less-touristy, more every-day part of Paris. The apartment was comfortable and clean, and we felt safe staying there. Returning at the end of a day sightseeing seemed like returning to an artist's colony, between the vintage courtyard and activity with a nearby actors' group.
There are a few advantages to the location of this Airbnb:
1. It's a short walk from a Metro station.
2. It's a short walk from a good grocery store (for those who want to buy additional items, make a meal, etc.)
3. There are some nice cafes on the same street as the apartment. We tried four of them over the course of the week and enjoyed all of them.
4. Although there is no air conditioning, the way the apartment is situated is naturally cooler than the outdoors, which was nice after a 90 F degree day of walking around.
5. There's a bakery across the street. I liked their raspberry tart best.
6. It's maybe 20-30 minutes by walking/Metro from most key sight-seeing locations in Paris (Louvre, Notre Dame, Montmarte, etc.).
Our host clearly communicated directions for arrival. We had a small issue finding the number for the building (which is small and very high up, so look carefully), but we were able to make a call that was immediately taken and we were given directions to find our way.
Overall, we had a good stay. If you're looking for a Paris stay that's more authentic and less commercialized, this place might be for you.
