As I recall it the airport is not very far, I guess some 4 miles
from the heart of the city and taxis are not expensive in Lisbon.
My guide book has the phone for airport information as 01/840-20-60 or
01/840-22-62 also says that Aero Bus costing 420 escudos which is very
little - a couple of dollars goes between the airport and the Cais do Sodre
train station from 7 am to 9 pm, every twenty minutes, however it makes
10 intermediate stops.
I would simply take a taxi, if I am not wrong they were aprox. 9 to 10
Graziella Miami Beach.
