I highly recommend Audrey's apartment for short to medium-term stays. It is tiny but comes exactly as described and has everything you need to make yourself at home: comfortable bed, desk, shower, fridge, stove, microwave, and best of all a fantastic view of the Parisian rooftops. The view at twilight was truly a great sight to behold and soak in.

The immediate area surrounding the apartment is safe and is very close to 2 convenient metro lines, from which one can arrive basically anywhere in central Paris within 30 mins. (The place itself is less than 10 min walk to Sacre Coeur Basilica in the heart of Montmartre) There is grocery shopping and virtually everything you need within 1-2 mins walk. Finally, Audrey is a very efficient and kind host.

This is a great place from which to spend a couple weeks or months in Paris.
