This apartment is in an UNBEATABLE location. I lived in Paris for many years, in different parts of the city, and can say that finding affordable housing in this particular area of the 9th arrondissement is like stumbling on buried treasure. I rented Charlotte's place for a full month, taking advantage of her great one-month discount, however even her normal nightly rate is superb.
When I say every type of shop you need is in an 8-minute walking distance, I mean it. There are multiple grocery stores, from Marks & Spencers to Monoprix. DO NOT miss out on Lafayette Gourmet, which is my favorite food shopping spot in all of Paris, and is literally a 5-minute walk from the apartment. Boulangerie Chez Meunier has a counter on the main floor with literally the best French pastries you will find. Trust me. Go there. Even my French friends had never heard of chausson au citron (basically a lemon turnover, in American lingo) and were blown away.
A métro stop is also within 8-minutes walking distance, making travel to every corner of the city a breeze. That said, the location of the 9th is such that, when the weather is good for walking, you can wander in any direction and stumble upon some of Paris's more famous landmarks.
The apartment itself is spotless, and very spacious for a Paris studio. The bathroom and shower are modern, clean, and updated. Staying there for a month meant that I made lots of use of the laundry machine. It is easy to dry your laundry on the heated bathroom rack, too.
The kitchen is spacious and minimal, with all the dishes and tools you will need (including a dishwasher). As stated above, grocery shopping is a breeze, so you can easily use the kitchen just as you would at home. For coffee, there is a French press, which is what I generally prefer anyway. If you're a tea person, there is an electric kettle, too.
The building neighbors are very quiet and discrete. In my weeks there, I only passed a couple of them in the hall, and had no noise issues. There are some street noises through the window but hey, that is part of city life and I don't mind it at all!
I will DEFINITELY try to book this apartment again in the future. 10/10 for sure.
P.S. The wifi is also very fast and reliable, if that is as big a concern for you as it was for me. :)
