You get what you pay for - this is a place to stay if you are on a very very tight budget. Otherwise I recommend you spend a bit more to get something in a better location that is more clean. That is what I decided to do after two almost sleepless nights at this place.
The shower was very clean, but the blankets were very dirty old fleece blankets covered in what looked like other people’s hair, dust bunnies, and/or dog hair. The room smelled like stale cigarettes. The other guests were very loud, I was woken at 5:30 am by two women having a screaming match next door. The area was just not what you have in mind when visiting Paris for vacation. Very low income and loud.
However, Lena the host was very nice. Overall a place to stay ONLY if you absolutely can’t afford more. I ended up leaving after day two to stay at another Airbnb.
