The atmosphere of the hostel is nice. Close to RER B metro that goes to the city, as well as not too bad of a walk to M14 for ORLY airport.
Staff service was fine, no one was rude or overly polite either. They didn't really tell me much other than how to get to my room, but they are there to answer questions.
The bartender was friendlier, drinks were good, and food from the kitchen was actually decent too!
There seems to be a lot of non-guests coming around for social drinks/food and using their meeting rooms. This isn't a bad thing, but more of an fyi, it can get crowded and lively with locals especially in the patio area.
I liked that the bed had its own blinds so you can get some privacy. And you can open the window in the room so it doesn't get stuffy or too stinky.
Shower pressure was good, but the drain is slow. I wouldn't say the room felt super clean, but it wasn't the worst or anything.
Another thing to note, you gotta plug in your room card by the door to keep the lights in the bathrooms/showers on.
The rooftop is small, but got a nice view. Also got laundry and little kitchen to use.
Luggage storage was about €5/bag.
