Pros- quite cheap, near stations
Cons- when you go out, you have to be back by 1:00am or doors locked, I was made to hand my key in when ever I went out but other guests weren’t, not sure why. The area the hotel is in is not that safe, the walls are paper thin can hear everything going on around.
That being said you get what you pay for, and it was fine for me! If you want to feel safe, stay more central in Paris!
