All of the other good reviews are spot-on. Gonçalo is a wonderful host. The apartment is comfortable, in a good neighborhood, and has everything. The back terrace is great for having dinner. We stayed here with another couple and we had a great night eating vegan Indian food from around the corner and drinking vinho verde out on the terrace. Alfama is pretty walkable and our host provided a bunch of emails with his local's knowledge and opinions including best places to eat, hear fado music, and best rooftop bars. And he greeted us with delicious pastel de nata and local wine. I wouldn't hesitate to stay at one of Gonçalo's places again.
