We are very satisfied with Helena apartment. It's very spacious, pleasant and right for the family. It's stay on quiet location belowe the Alfama (15 minutes by walk) with a little market downstairs and a bus station near by. But you don't need the bus, because the apartment is just about 10 to 15 minutes to Rossio by walk. Grete location. Aha, and it has a nice terrace on the roof. Helena was a great host. She help us with lot of the tips and others. And shes pitas was great. :)
