Overall: Wonderful apartment in the heart of Alfama, compact layout and well equipped. Quiet area at night once fado singers wrap up, and a great spot to explore old Lisbon from. Hosts were responsive to fixing the couple issues that came up.
Cons: Internet upload speed was slow enough to make video calls challenging, so consider a hotspot if that's important for you. And being at the center of things, the singing, tourists, and trash pick-up can leave the neighborhood somewhat loud until relatively late at night.
