This apartment deserves like 7 stars for the value you get for its price! You have to know what to expect, though -- this place is perfect for you if you are comfortable taking public transportation and don't mind living in a neighborhood that is not the sort of storybook Parisian neighborhood you see in the center; it's just a 'normal' middle class, 20th century-constructed neighborhood.
We would walk 3 minutes to the RER B line in the morning, take the train anywhere from about 7 min to maybe 12 min to get to the right bank, spend all day sightseeing, and have a short walk past a grocery store in the evening.
The bed was comfortable, you can see the Eiffel Tower from the balcony, and the kitchen was well-appointed. The neighborhood is comfortable, we felt safe all over, and there's even a mall if, like us, the airline loses your luggage for three days. Fortunately, the apartment had all the necessaries for us -- soap, shampoo, *laundry soap*, etc. If you are looking for an inexpensive but comfortable way to see Paris, and you don't mind public transportation (get a Navigo card at CDG before you leave!), this is a great choice.
