The Appartment from Guillaume was perfect for our journey. The description of the check in procedure was also excellent.
In the Appartment everything was lovely renovated and very clean.
Guillaume answered all our questions within minutes and the best thing was that we could leave our luggage in the Appartment til our train left in the afternoon.
The location itself in the heart of Montmartre was great. I will recommend this Appartment to my friends who are going to visit Paris.
