Rui responded quickly to my queries. He very kindly let us use a spare apt for the day as we had a very late flight. The apt is not in the centre of all the activity but travel is very quick, efficient and easy. Buy a day ticket for train, tram and bus for 6E a day. Its worth exploring the local restaurants for cheap but delicious food. We came across several very cloise to the apt which I didn't find at first as they are so unassuming. Highly recommend a day trip, or two, to Cascasis.
Enjoy you trip to Lisbon, I will certainly return to this friendly country.
