Isabelle's apartment was perfect for my situation as a two-month study abroad program student.
Location: There were two train stations to get basically anywhere in Paris, a large grocery store, several small grocery stores, ten or more restaurants, and two bus stops within five minutes walking from the apartment. There is also a police station about 200/300 yards from the apartment, so the neighborhood is safe.
Amenities: There is an elevator to the apartment floor, an electric key fob that gets you through the main two doors to the elevators, and then a key for the apartment door. There is a washer and dryer, WiFi, nice television with cable, dishwasher, beautiful balcony with pretty views, and one of the best showers I have ever used (I wish I had that shower in my personal apartment). Also a very nice Dyson fan to help with the heat.
Communication: Isabelle was incredibly nice and quick with her responses. I was greeted upon arrival and walked around the apartment and shown how everything works. When I had issues with the internet, Isabelle's husband messaged me and walked me through how to solve the issue.
The apartment itself: Newly redone and very well furnished. Comfortable eating area, comfortable bed. When I first got to the apartment, I thought there was a lack of outlets/plugs for my electronics, but they are just in places that I didn't notice at first. You will find them, and there are plenty. There were plenty of towels.
Apartment Layout: The bathroom (toilet and sink) and washer/dryer is on the level where you walk into the apartment, then you walk down a few steps to the main living area where the living room and kitchen are, then there are a few more steps down to the bedroom and the shower (shower and two sinks). This was a little weird at first, but got used to it very quickly.
If you are there as a student, an individual traveler, or a couple, the apartment is a great place for you.
The only downside for me was I was there for all of June and July, so the apartment got pretty warm due to the weather. However, I knew beforehand that there was no air conditioning (like basically all of Paris), so I knew what I was getting myself into. But you can open the doors to the balcony, and the windows in the bedroom to get a decent cross breeze. In non-Summer months this wouldn't be an issue. Also, the window in the bedroom (which I needed to keep open due to heat) made it somewhat loud at night due to street traffic, but I used a white-noise machine (which I always do, no matter what) so it was not a real issue for me.
If I were going back to Paris, I would definitely stay in Isabelle's beautiful apartment again. Thank you for a wonderful stay!
