I really enjoyed my stay at this apartment, it was small but had everything you could need. I stayed for 3 weeks and found it perfect, even though the kitchen was small it had all I needed to cook simple meals. The location was absolutely fantastic, right next to the metro or a walk to about everything you could want to see. The supermarket right next door was also very handy. The Murphy bed is quite comfy, I think it might be memory foam as you kind of sink in. The pillows were a little lumpy but nothing to bad. Only thing I will mention that wasn't great was the wifi. It was extremely spotty, dropping all the time and when it was there, the signal was very low. So if you plan to work online while you are in Paris this might not be the place for you.
I would recommend this place to any single or couple, it really ticks all the boxs
