Firstly, the location of the hotel was perfect, being a five minute walk along busy, commercial streets from the Gare du Nord. It felt very safe, even as tourists with kids and bags. There were plenty of restaurants in the area, from chains to bistros, and it was a 10 to 15 minute walk to Sacré Coeur and Montmatre (my personal favourite area of Paris.)
The room was pretty much exactly what we paid for, with decent beds. However, the bathroom was far too small such that a piece of wood had been cut out of the door so that it could be opened past the toilet!
Otherwise, the room was clean and the beds were comfortable. It was perfect for a brief overnight stay and I think would also work well for a base for a long weekend in Paris.
