Overall, I felt I got what I paid for at this venue. The hosts are very good at communicating, are there every day to clean and tidy, and give good instructions for getting in and out of the building. The water gets very nice and hot, there is one bathroom with a shower and toilet and another with a toilet, so I never had to wait long to use the restroom. There is a small area for basic cooking (not many dishes provided though). There is a fridge and a microwave and small lockers. There is a washer and dryer, but you do have to pay 3 euro's per load. It is a bit cramped, but I don't feel unexpectedly so in Paris for the nightly rate they charged.
The only real difficulty I had was with check in. It would be pretty difficult to find this place on your own, so the host meets with you at a nearby KFC. Being a foreign traveler, I could not call her on my phone, so (per her advice) I tried to get on the KFC wi-fi to message her via Air BnB. The KFC wi-fi wasn't working for me, so I went to a McDonald's across the street, but was still having issues. Thankfully a man sitting next to me let me borrow his phone to call the host. It all worked out in the end, but I was a little nervous about it.
