A nice place to stay in the heart of it all. You can't get more central than this.
If you're planning to visit Paris for its main attractions, the location is excellent for this, as it's a minute away from a fantastic subway station, 5 minutes walking distance from the Louvre, 15 minutes away from Notre-Dame etc. Plenty of restaurants, to experience almost any form of cuisine imaginable. If you prefer cooking, there's two grocery stores very close-by, and plenty of smaller fruit and vegetable markets around as well.
One thing you may want to be aware of however: since the apartment is so central, in a busy neighborhood, there's going to be a lot of noise in the evenings, especially with the windows open. If you're a light sleeper you probably want to bring some earplugs with you. But at least there's some thick curtains blocking a fair bit of light, so sleeping in the afternoon's if you're jetlagged is a bit easier.
