If you're looking for a room to put your head down for a night then you will be happy with it. It's clean and got relatively comfortable beds. However if you're looking for a relaxing stay then this is not for you, especially when staying in the rooms overlooking the main road. We got woken up few times at night by the city noise. The rooms overlooking the garden are much quieter, so try to stay on that side.
The rooms are small and quite dated.
I stayed there with my fiancée and it wasn't what we were looking for but it's close to Gare du Nord, so perfect location if you're pit stopping.
Breakfast is basic cost about €10, which is ok comparing to cafes.
