I trully recommend staying in that appartement. The neighborhood is nice, clean and safe and metro is very close. But above all appartement is very nice and comfortable and clean, it is exactly as on the pictures. We only met Emmanuel, who is the friendliest host I could imagine. He responds very fast on the email and helps with the tips about Paris, directions how to get somewhere, etc.
Thank you for everything, when I come back to Paris I will definitly contact you if the rooms are available :)
Wish you all the best, Ana
