Apartment is nice, but needs a bit more care. Lights in the living room didn't work, some plug sockets in sleeping room also didn't. Internet connection was slow and didn't work at all from time to time, which was not really handy. And cleaning could have been better, but in general it was ok.
Toilet is, like, super tiny (it's very difficult to see it on pictures), and if you're tall - beware of a cabinet on the wall on your left. Your head will most likely hit it when you stand up. Happened to me twice. Glass wall in the shower is kinda useless and only helps to spread water around, not keeping it inside of the shower cabin.
Location is great and easy to find; there're lots of shops and cafes nearby, subway stations within 5 minutes walking distance. But... it's not quiet at all. You'll certainly hear the music from all these cafes nearby ;) (moreover, the fridge in the kitchen also makes lots of noise!)
It's a good value for your money, considering prices in Paris, but my expectations were a bit higher...
