I wanted to like this place but I just cannot.
Very small space, especially with the airbed in place. It blocked the entry to the shower. This space was more of a small room/dorm than a studio. Not ideal for two average sized people. My friend and I are petite, under 5'5" and we had to shimmy around each other. Go alone to this space.
Toilet is in a closet and not comfortable, it's in the hall where all residents of the floor use it (not other travellers, residents).
Room smells of smoke (which may very well be very Parisian), so if you don't mind, no problem, but I hated it and it made me feel very disgusted, especially since the smell followed me on my clothes to the airport.
The beds were uncomfortable. Mine was like sleeping on the metal bar frame itself while my friend refused to move in the night because the airbed made so much noise.
