Wow! Jo&Joe Paris is amazing. It was in the outskirts of town, so a bit quieter--but keep that in mind because if you're trying to be closer to city center, you'll need to walk a long ways or get a metro ticket. The lounge space was awesome! I didn't go to the rooftop, so I can't speak to that space. The dorm was SUPER comfy! The bed was comfy, the shade was a great personal touch, and the outlets worked. Oh, and it was also quiet! And no smoking was allowed which I really appreciated. I loved being able to come back and feel like it was a functional space... that I didn't need to retreat to my bunk bed to hang out there. I used the downstairs lounge space quite a bit, working remotely and drinking my espresso's. The staff are really nice too! I highly recommend this place!
