ALSA BUS 的车站地点

ALSA BUS 的车站地点
定了ALSA 的夜BUS,2:00--7:00,从萨拉曼卡到葡萄牙的波尔图，可查不到这两个地方的汽车站是在哪里，从车站怎么到市中心，是走路还是坐车?这半夜里还有车可以坐嘛？哪位熟悉的朋友可以告知一下，谢谢了。:-D

Estación de Avenida de América and Estación del Sur have subway stops (Avenida de América and Méndez Álvaro) that leave you right at the station. The Auto Res station is within a two-minute walk of the closer subway stop. If you intend to go to Segovia, take the subway to the Príncipe Pío stop, get the Paseo de la Florida exit and walk on the left-hand side of the street until you get to La Sepulvedana. There are several smaller stations, however, so inquire at travel agencies for the one serving your destination.
