This is an amazing apartment located in the middle of Paris (7eme arrondissement, bordering the 15th). The bedrooms are located on a Parisian-style mezzanine (common for older apartments in Paris), so you would definitely need to crouch in order to access it. In case the photos aren't clear, there is a queen-sized bed on the mezzanine overlooking the living room. In addition, there is also a more private room with a single bed that offers more privacy, although it might get too hot in the summer. Other than that, it is a perfectly decent living space for 2 people for a long-term stay, especially for students (if need be, you could even squeeze 3 if you really want - although the sofa is not a sofa bed, but there is a pullout mattress underneath.)
Location wise - perfect, although keep in mind it is a relatively expensive area. However, there are affordable supermarkets (Carrefour City) a short distance away. Although it is in the centre of Paris, the street it's on is very quiet and safe at night.
Furnishing wise - the apartment is decked out in little paintings and shelves are full of books, giving a very cosy and quaint atmosphere. The toilet/bathroom is decently sized and fully functioning, with a hot shower. The kitchen is well stocked and has many utensils, cutlery, and cooking appliances. There are adequate cleaning appliances as well, and a good washing machine.
Others - there is a guardienne who lives opposite the apartment. Keep in mind she only speaks French. But she will always deliver your mail promptly/keep the common areas clean.
Living here, you will walk past Invalides and the Eiffel Tower every single day. You will absorb that spectacular Parisian atmosphere and think about what a beautiful city it is. You certainly can't get a more Parisian experience than this!
