Cons:
Front door locked late at night and early in morning, you need to ring the bell and wait for someone to come, even you have the access card to your room. I believe it is a matter of security, if you know about Paris
The water will not be refilled everyday for your consecutive stay.
Water heater was Broken and took over a night to fix, I believe this is just an single incident
Pros:
Clean and tidy room, although it is basic requirement
Great location next to metro and easy accessibility, public order is good, will supermarket, stores, restaurants, take away food nearby, close to Tour Eiffel.
Generally friendly staffs
