Old, old old, windy cobblestone streets. hills, Narrow alleys with old houses on top of each other.
Laundry hanging outside windows to dry. Old ladies in black talking to passerbys from their windows. Graffiti everywhere,
I wouldnt stay here (maybe 1-2 days) but definitley fun to visit, great fado clubs and authentic food.
Also, a note-- I felt very safe there (I had read about some not feeling so)
