Porto's longest-running coworking space, open since 2010, three minutes from Casa da Música metro. Big windows, dedicated phone booths (one shaped like an aquarium, genuinely), shower if you bike or run, and a chill-out room. Day passes available. It's the corporate-quiet end of the spectrum — not a community-events space, more a get-things-done one. Get a day pass from reception. Around €12 for a flexible desk; €100/month for full hot-desk access.
