The apartment was quite small (literally just a small living room and a bedroom with a bathroom attached), but we managed with 5 people. The sofa bed was surprisingly comfortable for us and the linens were all very nice. The bathroom smelled a bit off throughout the stay, so we kept its door closed. We also didn't use the washing machine because the closet it was in smelled really bad. The apartment was pretty cool in temperature while we slept there, despite being in Paris during the middle of the summer. The place doesn't have A/C, so it might be too warm if Paris is super hot during your stay.
