Hi Geri Máté,
Great to hear about your Web Summit plans! While I can't be there, here are suggestions on What to do in Lisbon. Explore historic sites like Belém Tower and Jerónimos Monastery, wander through Alfama's charming streets, experience Bairro Alto's vibrant nightlife, take Tram 28 for a scenic tour, and savor local cuisine—especially the famous Pastéis de Nata. Enjoy your time in Lisbon, and I'm sure your team will have a fantastic summit experience
