Check out the nightlife in Bairro Alto: this neighbourhood is filled with cool cafés, bars and clubs, many of which can be found along Rua de Italia and Rua da Barroca.
Listen to some ‘fado’ music. Explore the Alfama neighbourhood: Not only is it home to attractions like Sé Cathedral and Castelo de Sao Jorge along with ‘fado’ bars, it’s also got plenty of narrow streets for you to explore while you check out the area’s Moorish influences.
Organize your day very well. If you want to visit Belém, be sure you wake up early and you'll spend there all the morning; Never try to visit Lisbon's best attractions (Belém, Castelo de São Jorge, Baixa, Parque das Nações) on the same day!
