Lisbon to me personally was the best citytrip I have ever done ! Forget Barcelona and Paris, really this city has so much nice places, viewpoints and also the area outside Lisbon is very nice. After visiting different areas of the city like Baixa and Alfama I also did a day excursion to Pena,Sintra and Cascais. It’s also the city where I took for the first time the Touristic “Hop on Hop off Bus”. There are 3 lines, blue, red and green, I did them all 3 as I had enough days planned for this citytrip. The streets in Lisbon go up and down, just like San Francisco. Famous sightseeing in Lisbon are the following : Elevador de Santa Lucia,Praça de Marquês de Pombal,Praça de Comercio,Se Cathedral,Palacio de Sao Bento, Sao Vicente de Fora church,Jeronimos Monastery,Belem Tower,Padrao dos Descobrimentos.
I also visited the football stadium of Benfica Lisbon with the Eusebio statue at the outside, the best football player Portugal ever had.
