Caroline’s apartment is the best! I stayed at several airbnbs during my trip and it was my favorite. It’s well located near the Bastille metro stop and with numerous shops and bars/restaurants around it. However, being a few floors up and looking into the courtyard, it was still peacefully quiet. Impeccably clean and beautifully decorated, staying in this spacious (by paris standards) apartment was a treat! Also, as a female traveling alone I felt very safe.
