This was a great spot for my last-minute solo Paris trip. The location is great -- close to public transportation for getting around and to and from the airports. It is very close to the Eiffel Tower and I walked all over Paris from here.
For my type of traveling, this was a perfect place: I'm not looking for a place to spend hours sitting and relaxing, just a place to sleep and keep my things safe while I am out and about. It is small (maybe 8' x 12'?) and the shower is about 2' x 2'. I didn't use them, but saw there are some plates, silverware and a couple pans to use with the hotplate. Salt, pepper and garlic. There is a microwave (didn't use) and small refrigerator which worked well. There is some sort of coffee machine (looked like little k-cups?) which I also didn't use. There is no Wi-Fi, so plan accordingly. So, it is very basic but that is all I wanted and it was priced nicely.
One note about the bathroom. It took me several nights to realize that the door to the toilet was banging throughout the night - I just thought a lot of people were using it :) I started closing the window on my last trip to the toilet each night and got much better sleep!
Overall, the location, price and amenities were all just what I was looking for to keep this impromptu Paris trip within my limited budget. I would recommend it to anyone looking for a place to sleep and would stay here if I am ever in Paris alone again.
