The apartment is far better than described. It is very, very close to Paris Nord, but not noisy at night. 5 min walk maximum to nearby bus and metro stations. Everything is clean, decorated in a modern style. You can find any kind of restaurants, supermarkets, cafes, fruit shops just downstairs. Very convenient. 20 min walk from Lafayette, and 25 min from the Louvre. We walked both times, and it was great.
Ines was very attentive of us in telling us where everything is, and was very fast in responding to our questions. There is a lift in the building, so we didn't have to drag our luggage upstairs.
The only downside of the apartment is there is no wifi.
All in all, my friend and I had a great stay at Ines', and we would definitely recommend it.
