As a couple, Miradouro de Santa Luzia works.
The prettiest-framed of Lisbon's viewpoints — bougainvillea, blue-and-white azulejo panels and a pergola over the Alfama tumble to the river. The catch: it's small, on every tour itinerary, and so packed mid-day that getting an unobstructed photo takes patience. Early morning it's almost yours.
