The room was clean and well made upon arrival. We were never distributed by other guests or staff members.

The location could have been better for the trip I planned but that is ti no fault of the facility.

Merci au manager Emmanuel qui a été tres sympathique avec moi. La propreté, le lit, la présence de café.

Il faut prendre obligatoire un bus ( le 70 ou 71) pour prendre la ligne rouge du metro si vous n'avez pas de voiture, ce qui était mon cas. Mais les bus sont nombreux même le soir.
