The room is small. If you're traveling alone like I was it works just fine. The shower and bathroom are even smaller. If you're a bigger person you will find both difficult to navigate. It's just down the street from the Opera Bastille.
The good:
Great location, decent price and safe neighborhood.
The bad:
The entire building seems to be temporary housing so you can have either quiet, respectful neighbors or several nights when the gendarmes are called out for disturbances. This is luck of the draw for any BNB in an apartment complex.
The ugly:
I don't have many complaints. The room was what was advertised, fairly priced and checking out/in was easy.
The shower was poorly planned and leaked during use. The space for it is very small and knobs would have been a much better choice than a push lever. I hit it a lot when I turned around either shutting it off completely or ramming it over to too hot or too cold.
