Considering the price of the position (€360/month), this is one of the worst coworking spaces I've ever encountered in Paris. The office reserved for coworkers has only one window overlooking a ventilation shaft, making it dark (and gloomy, see photos). Several private offices or meeting rooms don't even have... windows! Regarding on-site services, the coworking space doesn't have a printer or photocopier: it almost sounds like a joke. Not enough meeting rooms or phone boxes: you make 50% of your calls in the hallway (also windowless). No self-service tea. Lose your access card? It'll cost you €20! They don't ask for a gold-plated card... Anyway.
The worst part was when we wanted to leave the coworking space because our team had grown from 1 to 6 people. We had to give it 2 months' notice, even though some people had been there for less than a month! For an offer marketed as "nomadic," it feels more like a hostage situation. The sales team showed no agility, even though they couldn't find us a private office solution (with a window, if that's not too much to ask for, and centrally located in Paris).
A few positive points (because they're needed): the rooftop is nice, as is the ground floor room. It's still meager, though.
