This was an absolutely incredible AirBnB.
I stayed for three weeks in December. Although the location is spectacular (in the heart of the 11th, with Oberkampf/Canal Saint-Martin/Republique within minutes away), I will only talk about Assif's space.
The check-in was extremely smooth with no issues. I was immediately stunned by how much larger the space was than expected. For the price, I think the value is extremely high - the living room/bedroom is large, the kitchen is perfect for one or two people to cook, the bathroom is accessible, and the shower room is spacious as well.
The living room/bedroom is wonderfully cozy. The wallpaper, decorations, chairs, and bed create a great atmosphere to relax or read in.
The only concern I had going in was the sound. Although there certainly is noise at night, I adapted within a day or two and had no trouble sleeping at all throughout my stay. The noise is only loud on Fridays or Saturdays, and during the week at night it is quiet.
Overall, I would highly recommend this space if you have the opportunity to book it. The combination of a wonderful location and cozy home-base make it a wonderful foundation to any trip to Paris!
