Just below the Pantheon, close to the thieves market (so stay including Tuesday or Saturday), get help to buy a travel ticket and walk up the hill from San Sebastio, Gulbenkian and the Tile Museum were my choices for a full-on visit. Wear strong shoes or good trainers, Lisboa is a mass of steep hills. The TV is mostly the news, has a good international coverage, mostly depressing for a European minded Englishman!
