A great little apartment with a wonderful host.
Pros - Arnaud was very responsive and looked after us really well. Very close to several metro stations, dining in Montmartre and Sacre Coeur basillica. Apartment is small but has everything you need - comfy bed, hot shower, washing machine, kitchenette, wifi.
Cons - walls are thin, but typical for a Parisian apartment! Dodgy people around, but again just typical for the area.
Would definitely stay again!
