This apartment is perfect if you're a solo traveler or perhaps a small couple who are very comfortable with sharing a small bed. The bed is a twin mattress, and as a tall guy I haven't slept in a bed that size since high school, but as I was only there for 3 nights and spent most of my time sightseeing and--let's be real--eating and drinking, it was wonderful to have a warm, clean, charming little slice of Paris to come back to at night. It's on the eighth floor of the building, but there's an elevator, and you get some quite nice views of the neighborhood from the windows, especially at sundown. The wifi was conistent, it's got a little kitchenette if you really want to cook yourself something or keep something cold in the fridge, and the heat from the radiator kept me nice and toasty on those 28 to 30 degree nights while I was there.
Marie is very communicative and friendly; upon my arrival she invited me to her own apartment on the other side of the building for a glass of wine, a chat about what I'm interested in about Paris, and then proceeded to give me a map of the city and metro system covered in helpful tips about museums I might enjoy, beautiful walks around the city, her favorite places to eat, and great places to get wine--all of which proved to be excellent recommendations.
The neighborhood itself is easily accessible via the metro, so getting to and from places all over Paris and back to the apartment was super easy, and it's full of cafe's, flower shops, boulangeries, pharmacies, and all manner of late night food as well. I'd definitely look this place up if I were ever traveling to Paris again!
