Wonderful place to stay when exploring Lisbon! You are near top of a hill and can easily walk your way down to see the sites in the center of the city (take Tram 28 to get back up the hill).
The place is well equipped to make a meal with markets close by.
With a major lookout/park only a couple blocks away, each evening we enjoyed the view with a book and beverage as the sun went down...very relaxing!
