Apartment is very nice - cozy and clean. It's in amazing location, very close to everything. Metro station (which is also a straight RER line to CDG airport) is within 5 minutes walk. A Carrefour supermarket that works until 10 p.m. is right near the house.
The kitchen has everything you might need, including a fridge, a microwave, a kettle. We also had some tea bags and some food in the fridge that host has put there.
Everything was clean and comfortable, we really enjoyed our stay there and had absolutely no worries.
One note only: if you are obese, you might get some trouble with a shower, the door is narrow.
