Lisbon

Hills, a yellow tram, and dinner a street back from the river. Walkable, and priced before you book.

Good to know

Go: Stay in Baixa if you want flat streets. Alfama is the walk, not the base.
Skip: Skip a river dinner with a cover charge. The same fish costs less two streets back.
Eat: A bifana or grilled fish in Mouraria. Sit where the menu is shorter than the queue.
Entry: Schengen rules depend on your passport. Many can enter for a short stay without a visa. Check the length before you book.
Timing: July and August are hot, and the hills are packed by noon. May, September are easier.

Tram 28, early
$4
Alfama · morning
Ride it before ten. After that you are standing in a doorway.
A miradouro at the end of the day
Free
Alfama · evening
Portas do Sol or Senhora do Monte. Bring water, not a reservation.
Time Out Market, one stall
$18
Baixa · afternoon
Pick one stall. Circling with a second plate is how the bill grows.
Belem in the morning
$8
Belem · morning
The monastery ticket is the cost. The custard tart next door is separate.
River path by bike
$15
Belem · afternoon
Rent in Belem, not in the hills. The path is flat on purpose.
Bairro Alto after dark
$20
Bairro Alto · evening
One drink on the street. The clubs are a different budget.
LX Factory
Free
Belem · afternoon
The bookshops are free. The brunch line is not the point.
A short cooking class
$45
Baixa · morning
Pick one that shops first. The market is the useful part.

A typical cost in US dollars, so you can decide before you open a booking site. Not a live fare.
