The place is nicely decorated, and has all sorts of necessities. Also the location is great, easy to get anywhere in Paris using the metro.
As for remarks to know beforehand, there are no proper curtains, so bring a sleeping mask. The sofa bed is not fit for a good sleep. The dedicated working space is tiny and missing a decent chair.
So all in all the place is a great fit for a short stay to visit Paris, and the place is nice and quiet with the windows closed.
