I confirm all the previous good reviews: Fiona is one of the best hosts ever.
I met her only at the end of my stay, but she has always been present, sending me frequent messages (even if everything is well explained on her Airbnb page), or replying quickly to anything I needed.
Her place is comfortable, clean, quiet and placed in a safe zone of the city, from where you can get easily to the center (the metro stops Thieffry or Petillon are placed at a walkable distance) or any other place by tram or bus.
I strongly recommend this accomodation, Fiona takes care of her guests like a friend, she has also very interesting things to tell and a beautiful laugh!
