I stayed with Reda for a week, and you cannot get a better location if you want a local neighborhood feel. Reda's place is close to the metro and very walkable to everything you might need in Paris. Reda was so friendly, offering suggestions on cafes, places to work, and restaurants I might enjoy.
The room is cozy, and if you are just looking for a place to sleep and shower in the middle of everything, Reda's place is perfect. If I am being honest, I did not feel comfortable using her apartment's living or kitchen area, which might be my only complaint outside of the noise that others have mentioned. Regardless, it was a fantastic week, and Reda was so polite and accommodating.
