Betahaus Barcelona

A serious coworking space for when the work actually matters — development, architecture diagrams, long documents, back-to-back calls. The day pass runs around €20 plus VAT, Monday to Friday 09:00–18:00, and includes 600 Mbps symmetric internet, ergonomic chairs, twenty call booths, coffee, tea, filtered water, and access to six terraces. Considerably better value than colonizing a café table all day while buying things you don't particularly want. The trade-off is location: Gràcia is pleasant but a real trip if you're based near the Gothic Quarter or the waterfront.
