My Girlfriend and I really enjoyed staying at Miriam&Didi's apartment. The metro-station Courcelles is very close by and the l'Arc de triomphe is just a 15min walk away. Communication with them was easy and they were very caring. We've just been there for sleeping anyway, the bed was comfy and the shower they have is great. Would definitely recommend it to every couple who want's to spend holidays in Paris and just needs a nice place to sleep.
