I had always stayed in hotels when in Paris, but this time I tried the Citadines aparthotel. Glad I did it!
The Citadines Austerlitz is in a quiet residential neighborhood just off of Vincent Auriol Blvd in the 13th Arr. This area has significantly improved over the past 10 yrs.
The studio apt has a fully equipped kitchenette with a microwave, refrigerator, stovetop, cutlery, utensils, dinnerware, etc. Also has dishsoap, dishtowel, sponge, garbage bags.
My unit had a balcony, which was nice.
Tip: There is no maid service for stays 6 days or less, but everything you need is in the apartment, or else easy to get from the front desk or housekeeping.
There are 2 supermarkets within a 5 minute walk ( Leader Price in Place Pinel and Carrefour Supermarket Paris Nationale just across Vincent Auriol Blvd). Both are low price. If you desire an Asian supermarket, then walk down to Place d'Italie, turn left onto Avenue de Choisy, and 1/2 block down on the left-hand side is Tang Freres Supermarche. They have everything!
Citadines has free coffee/tea available 24/7. There is also a garden with table/chairs.
It is close to Metro line 6- Nationale and Metro line 5- Campo Formio.
The wifi is fine.
There is a laundry room in the basement.
