The location disclose to Gare du Nord, which is convenient.
People literally walk past the 'living room' of the 'apartment' , which gives a lot of noise as do the neighbours. There is no real day light as the windows are sealed.
There is a glass container put to the window of one of the bedrooms, it is used during the night and early morning which wakes you up.
There was no hot water on 1 of 3 days we stayed, since it was the last we do not know if it could be fixed quickly.
