50 Mbps average — reliable enough for video calls, but verify before booking
Lisbon’s internet infrastructure is solid by European standards. Fiber (FTTH) covers most of the city center, and 4G/5G mobile data is fast. The 50 Mbps average reflects a mix of fiber apartments and older buildings still on DSL.

What to check before booking accommodation
- Ask for a Speedtest screenshot — actual speeds vary wildly between buildings. A fiber-connected apartment in Chiado might get 200 Mbps; a renovated flat in Alfama might top out at 20 Mbps on old copper.
- Check router placement — many Portuguese apartments have thick stone walls that kill WiFi signal. Ask if there’s a router in the work area.
- Backup connection — Portuguese mobile data is cheap and fast. Keep a local SIM or eSIM as fallback for important calls.

Coworking internet speeds
Most coworking spaces in Lisbon offer dedicated fiber connections running 100-300 Mbps. Expect symmetric speeds (upload matches download) — critical for video calls and screen sharing.
Spaces like Second Home, Impact Hub, and Heden typically guarantee minimum speeds in their terms. Ask before signing up.
Public WiFi
Free WiFi is available in most cafes, but speeds are unpredictable (5-30 Mbps). The Lisbon municipality offers free WiFi hotspots in major plazas and parks, though connection drops are common.
For reliable work: stick to your accommodation’s fiber connection or a coworking space. Use mobile data as backup.
