This Airbnb apartment is conveniently located in the Bastille area. The Metro is only two to three minutes walk away. There are heaps of supermarkets, shops, bakeries and bistros in the area, as well as an outdoor fruit and veg market (Marché d'Aligre). The Opéra Bastille, Blé Sucré (widely regarded to have the best madeleines in Paris) and Le Chocolat Alain Ducasse are within walking distance. It is also about 30 minuets stroll to Marais.
The apartment itself is nicely furnished and the photos are pretty accurate. The flat is equipped with everything you will need - iron, washing machine/dryer, coffee maker, shampoo, hair dryer etc.
As someone else mentioned, the bonus is that the flat is on the ground floor (which is great if you've been climbing stairs in other Paris apartments). However, you will hear people walking past. Having said that, I am a light sleeper and it never woke me up.
Paris was quite warm when we were there in September and what I loved about this flat was the windows/shutters which kept the heat out. I imagine they would keep the cold out in winter too.
Check in and check out was very easy. Christine was kind to personally show us the apartment, something that many Airbnb hosts dispense with. She had some pastry ready, another welcoming and personal touch. She was communicative throughout the stay and responded to queries within a couple of hours maximum. She also booked taxis to the airport for us, which was much appreciated.
The thing that stood out for me the most about Christine is that given that many Airbnb hosts now run their rentals like a faceless corporation, she was really human. It was very nice to have a human touch.
