Well~ I would say that if you have extremely limited budget you may consider this hotel. If not, please choose any other one. I feel disappointed with this hotel. There is 3 hotels located in Paris and you don't know which one you are going to stay until a week before you trip. They will send you an email to tell you. One is located near the Main Street and metro station while the other one is located nearby but in a quite street and difficult to find (I stayed in this one). The last one is located at another area. There are 2 supermarkets nearby, but I think this area isn't very safe. There are many drunk man around at night. Please be careful.
The room does not have toile, only the bathroom. Man and women share the same toilets. The cleanliness of toilets is ok....still acceptable. However, there is no air condition in the room, so it feels stuffy. Also the bed is not very clean and uncomfortable. It seems that the hotels is for the school trip/ something like that. Not very satisfied.
For the breakfast, everyday the same. A very very very hard bread with a cup of coffee/ orange juice. Some cornflakes with milk. You have no choice and no hot dishes.
For the staff, they are not helpful and impolite. There is a black fat woman in the reception, she is rude ( I am not racial discrimination, it is just because the attitude of that woman is very bad). It is not easy to borrow the hair dryer, it depends on the kindness of the staff. Some may not wanna help you.
