The apartment is located walking distance from the Louvre and was very convenient for walking everywhere we wanted to go. I am a non-smoking Californian who knows what to expect as far as smoking in Europe, however when I have stayed places in Europe (airbnb and hotel) it is usually a respite from smoking. I do not know if the owner is a smoker or someone else in the building is and it seeps through, but a heavy smell of smoke is present especially around the entrance and bathroom. It wasn't a huge problem I just think you may want to know as I found it unpleasant. The last security door leading to the apartment is in need of repair. You have to slam it to get it to latch and I always felt I was being rude by doing so when I went for breakfast as the host's sister lives right near this door.
