Positive sides:
Great location (close to the most important metro lines) and close to the center (for 20 mins walk you are in the most important landmarks)
Clean bedsheets and towels/ warm room
Good instructions and easy check in/out
Negative sides:
There are people leaving down the hallway, and there is quite some smell in the hall from their cooking, it was quite messy in the entrance since there is their kitchen/shoes and clothes
It can get noisy because of these people
The space is super small, doable for 3 people but wouldn’t do it again
There are no toothpaste or slippers provided, so you should bring them if you decide to go.
Overall perspective: ok for Paris since the accomodation prices don’t make sense at all in here, and the location was great. But I guess because of the lack of space and the mess/noise in the hallway because of the people who were living there, I wouldn’t do it again (or I would while bearing these disadvantages in mind).
