Nice apartment, well appointed and very functional. The kitchen with lots of equipment is nice, and the bathroom with a nice modern shower was also very appreciated. Just a little disappointed with the bed, which was very basic, with a 10cm wide mattress and a cheap box spring. I didn't sleep badly, but I could feel the slats, and I can't say I had a great sleep...
The other thing to note about this apartment is the isolation. The windows are only single glazed, so you share everything that happens on the street, even if you are on the third floor. The street is quite busy, and even with earplugs I was woken up by noise from the street or neighbors. It's also the same with the cold... it comes from all the windows and the front door. We had very cold nights and the electric heaters weren't really good enough...and it was only October, not the middle of Winter.
On the good side, the location is great. You can be everywhere in Paris in less than 30min by public transport. The neighborhood is safe, no problem getting back to the apartment late at night. You will also find many shops and restaurants nearby.
