I've used Airbnb all over the world, and Élodie is quite literally the best host I've ever encountered. She welcomed us in as if we were old friends on holiday at her home. She even stocked the fridge for us!!! Insane. I've never had that happen at any other Airbnb. Also, super nice that there's an elevator in the building (but if you're claustrophobic, don't rely on it), since it's on the 6th/top floor. The flat was so full of Parisian charm.
The only downsides worth mentioning: --no AC, which of course is typical for Paris. However, if you're visiting in the summer, there are plenty of windows you can leave open. But the street below is a main Boulevard in her neighborhood, so earplugs will be a must to sleep through the night with the windows open.
--also, location. This is a very residential neighborhood, which is what we wanted! However, we didn't realize it's about a 30 minute metro ride each way to the landmarks. Again, this isn't anything Élodie has control over, but just something to be aware of if you plan on spending lots of time near the major museums and sights.
Overall, this place is incredible considering the price. I can't say enough about Élodie, she's great, and if you're looking for a more residential experience in Paris, this is the place for you!
