The single bed was very comfortable and supportive, and everything was clean in the apartment. I stayed there when the hosts were away and there were other guests in the other bedroom, and there was never a problem. A Lidl supermarket is adjacent to the apartment, as well as bakeries, cafés, small places to get take-out food -- so it is super convenient. The street is not a grand boulevard but it does get traffic so there is the typical city street noise, so if you are very sensitive to noise at night you might want to consider that. I wore earplugs and had no problem sleeping (being jet-lagged and very tired helped!). It's Paris, so one should expect some noise anyway.
