Stay @ Porto的到达路线
Take the metro at the airport (purple line), exit in Trindade. You can walk if you want to the apartment as Trindade is in Rua de Camoes (you have to walk up the street about 1000 meters) but I will recommend you to take the Yellow line to Hospital Sao Joao and exit in Faria Guimaraes (about 200 meters from the apartment). The station exits in Rua Faria Guimares, go around the corner and walk to the other street were the cars go down and continue that street up (Rua de Camoes). The building is just in front of a big yellow building (Hospital Santa Maria).
