The apartment is clean and nice. There's a Metro station a two-minute walk away. Going to the major tourist sights is easy although it requires changing trains. There are also supermarkets within a reasonable walking distance.
For two people, there's enough space, but four people (two couples) might find it a bit small unless it's a short stay and they're comfortable with tight living conditions.
All in all, most people would probably find this a good place to stay in Paris for a shorter period of time.
