The apartment is well placed, Alfama is a good district ! It's not like Bairro Alto but you have also bar/restaurants not far from the apartment. And you can go to the center of Lisboa and Bairro Alto very quickly so it's Perfect. It was amazing to be next to the panthéon, this is very helpfull to go home vewing it far far away.
Conclusion: A very Nice apartment with Great views on the Panthéon and the Tage
