A different route from the IBIS Barata Salgueiro to Cais de Sodré, involves turning left out of the IBIS, continue up the hill, then bear left into Rua Nova de São Mamede, then left into Rua Escola Politecnica, continuing on down passing Praça do Príncipe Real, then on as the street becomes successively Rua Dom Pedro V, then Rua São Pedro de Alcantara, then Rua da Misericórdia, and then after Largo do Carmo, Rua Alecrim which carries straight on down to Cais de Sodré.
It's a different routing, but one can see places such as the Jardim do Príncipe Real, the Jardim do São Pedro de Alcantara with views over towards the Castle , and if one looks left while passing Largo do Carmo, one may just see through the crowds, the bronze of Fernando Pessoa sitting at his table in front of Cafe Brasileira.
