The studio is located in the 5th arrondissement of Paris, only a 5 minute walk from the metro line 5 and a 7 minute walk from the metro line 10 and RER C at Gare Austerlitz. This makes it really easy to get around any part of the city quickly and efficiently.
The studio is located on the 7th floor(American standard or 6th floor "European measurement") with no elevator. Although it can be quite a climb if you're here for a long stay the climb will become easier and easier and after a week or two it will hardly be noticeable. However, if you're physically disabled, have a hard time exercising or are older this place might not be for you.
The actual studio isn't huge and is much smaller than a typical American studio however it feels spacious enough for a student long stay, business trip, or short travel stay for two people. It comes with a separate bathroom in the studio which includes a squared small bath tub and a sink. The toilet is located outside the studio in the hallway. It also comes with a kitchenette comprising of a hot plate, a sink and several kitchenware such as plates, knives, a drainer etc. There is little cooking space, however I did not cook much during my stay so this wasn't much of an issue, if however you cook large meals often this may be inconvenient.
The bed is a decent size and is very comfortable, I had no trouble sleeping. The spot always comes with much closet space so storage wasn't an issue either. The bed can also be folded into a couch if more space is needed. It also comes with a desk and a chair which were very useful when doing homework.
Overall, in my 5 month stay I found the place to be perfect for my semester in Paris, it is conveniently located, spacious and well equipped for my studies. My only gripe would be that during the winter the spot can get very cold and the heater doesn't work very well, it can take a while to feel any warmth from the heater and it often doesn't fill the whole space. Sandra, however is willing to help by offering a fleece blanket if needed. She is a very kind, accommodating host, who responds quickly and is really there if you need her. I recommend this space to any students, or businessmen/women who are looking for a place to stay in Paris!
