Nice place! Yannick and her son were very helpful and Gerard was quite friendly too. The location is excellent as it is only two stops from Gare Du Nord. The hosts were very flexible with breakfast times. They were also kind on the last day to let my son and I leave our luggage until it was time to catch our train and also let us eat our takeaway at the house. Yannick also gave us bottles of water which was a nice thing to do. The room was nice and warm and the issue about its height is well documented.
The price was very good for the location. Montmarte and Sopigalle were within walking distance.
A good experience overall and recommended due to location, price, friendliness and helpfulness of the host. Tres acceuillant!
