Great spot! Place is ideal if you wanna use as a spot to leave your stuff and go and explore Paris (no one should stay indoors while visiting anyways). Perfect for 1 person, we were 2 and felt a bit crowded but nothing worth noting.
As many people have stated, be prepared to go 5-6 flights of stairs to go to the room (which we thought it was great exercise!) and don't be surprised if you hear the neighbors, walls are paper thin; however, none of this stopped us from loving this place, especially for this unbeatable price!
Finally, Eléonore was an amazing host, took care of our stuff, even carried one of our luggages throughout the stairs, reminded us that there was a heater we could use stored when it got very cold, and she was always smiling and willing to help! 5 stars for me :)
