Laure's Apartment is perfect. I stayed there with my girlfriend for 4 nights.
It's very close to Metro Station (line 12) so you can reach Montmatre in 10 min and the centre of Paris in 15-20 min.
The neighborhood is full of markets (I found 3 in less then 200m), boulangerie, bar, shops, restaurants, fast food.
It's quite safe even if you can meet some strange persons in the night, normal for a big city and we never had problems. Paris is full of police and it's the safest metropolis I visited.
The apartment is very warm and pretty. There's everything you need except for a TV but I never watch television at home.
The kitchen is well equipped and we could cook every evening without problems.
Wifi is good.
I had the possibility to meet Laure and she's a very kind and private. She was very caring to explain us the way to reach the apartment from the airport, giving us many informations about shops and so on.
If you need something, write a whatsapp message to her and any problem is solved.
When I'll come back to Paris I hope to stay in Laure's apartment again.
