This Airbnb is just not ready for people to live in. There is no ventilation, the accommodations felt unclean at best and the beds were only thin mats. Additionally, due to the fact that there is no ventilation or fans, there is definitely a mold problem in this place. Aside from the itchiness, irritated eyes, trouble breathing and coughing that my friend and I developed while inside of here, I found a cutting board completely covered in mold and was told to "just don't touch it."
The host was nice and helpful in describing the area, but also insisted on entering the space when we were not there despite us telling her we wanted to be there if anyone was going to be inside with our valuables. This is mostly because if the door is unlocked, people will simply walk in off the street thinking it is a store. You will see many people just standing around outside the door looking confused. The only real light in the place is the front door/windows (think of a first floor convenience store), which was mirrored film. During the day this works fine. However, at night if you have the lights on people can see straight in, even if you have the thin curtains closed. The other problem with the mirroring is that it doesn't go all the way down so someone could simply kneel down and look straight in.
The kitchen was alright, no real complaints there. One of the best parts about this place was that the mini fridge worked well and the freezer might have been the coldest one in all of Paris.
The bathroom felt unclean and was very small. The shower also felt unclean and the curtain lacked a liner. Because of this, the option was to have a shower curtain that was visibly dirty from people standing on it in the shower with you or for it to be outside of the shower, allowing the water out. The shower head not being connected to the wall did not help this.
We try to come into every stay with an open mind, but this Airbnb was in such poor condition that we decided to leave about a week early and stay elsewhere once we could afford it. With some renovations, this place could be really cool and unique. At the moment, though, it's pretty much just an unventilated box with furniture and other accommodations that seemed like someone pulled them out of a dumpster. Do yourself a favor and spend a little more money to find a nicer place. Staying here negatively impacted our trip (lack of sleep from the beds, feeling unclean from the lack of adequate shower, having to be outside all the time just so we could breath without sinus issues or coughing from the mold) to the point where we just couldn't enjoy ourselves.
