This location could not be better if you want to explore the old section of Lisbon. You are literally looking at the walls of Sao Jorge Castle on one side, and the red rooftops and Tagus river on the other. The balcony alone is worth the cost. It is walkable throughout the old sections of Lisbon, and moments from the 28 Trolley. It is a great value, and Joana is an exceptional host - even going out of her way to make possible a birthday suprise for my wife. 100% recommend. One note - If you have a rental car, I would not try to park nearby.. park outside of the castle area.
