Mounia's place is great for getting around the city.
It's a little smaller than what most American's might expect, but seeing as I was travelling solo, it worked out great.
Your bed is a pull-out style sofa. It's actually softer than what you'd expect, but not an actual bed. I had no problem falling asleep each night.
The bathroom has a step-in style tub. Again, no problem for me. But if you have any issues stepping up and over, then note that.
Also, there's a nice sitting area outside on the patio for morning coffee or reading, or if you need to hang some clothes (there's a washing machine as well!)
Mounia's place is in a great location to the RER and regular metro lines.
5-10 minute walk to either Metro Line 9, 1, or RER. Very convenient to any location in Paris.
