One of the best airbnb experiences we've ever had. The apartment is just as nice if not nicer than the photos, absolutely spotless, lots of great touches (including Netflix - it was nice to watch a movie after a long day walking all over town), a great and tranquil spot to serve as a base to explore Lisbon from. Great communication from Victor and very friendly and helpful reception from Olinda (though she only spoke Portuguese, but we managed).
The only thing to note is that it's a steep climb up from the already hilly streets of Alfama so not necessarily the most accessible apartment, but if you don't mind the hike this is a really unforgettable place. Thanks Victor.
