Pedro is the kind of guy you feel is a friend after ten minutes. He will tell you all you need/want to know about his Lisbon. Everything in his place is immaculate and he has a good selection of miscellaneous food stuffs to get you started. You can't ask for a better host!. The yellow tram goes right by. Take it up from down below. When you get off at the stop past "home" check the church and the monastery next door.
Fantastic location.
