Day 1
Start by visiting the Alfama district. There are free tours, as animated as they are full of surprises, that will give you an in-depth insight into the area. Walk through its streets, not forgetting to take the Feira da Ladra - a trail along which you can find everything: the national pantheon, the cathedral, the castle of San Jorge and the magnificent Santa Lucía viewing point. Descend to your next destination, and eat in any cafe in the Rua do Comercio area. Stop at A Brasileira to check out the statue of Fernando Pessoa, the immortal Lisbon writer.
Take advantage of the afternoon to go to the Plaza del Comercio, after seeing the Rossio square and riding the Elevador de Santa Justa, a lift that allows you to contemplate unique views of the river Tagus. Retrace your steps back up to Barrio Alto to dine in a typical locale.
