We were a party of 4 adults staying 4 nights here. It was a little crammed, but definitely doable and good value for 4 people.
We were overall happy with our stay - everything was clean and it was easy and convenient to find and check-in with the directions Glenn provided. I personally like this area of Paris, because it is a pretty local neighborhood but has plenty of options for going out or getting groceries (great bakery just up the street).
However, we were a bit disappointed that there were no basic things at all - like hand wash or a tab for the dishwasher. I get that there were not basics included, but it just felt a little too basic.
Would recommend for people looking for great value in a nice area of Paris that is not too touristy and who don't plan on doing any actual cooking.
