Wonderful neighborhood! It was right around the corner to Torre dos Clerigos, Livraria Lello, and a few old and beautiful touristic neighborhoods, close to Aliados subway station, and close to the river, many, many, many pretty churches.
Mr. Antonio recommended me a few close places to eat (including the ones with THE best pastel de natas I've had in all Porto).
About the place itself. My room was tiny, but nice for a student. I wish I had a small desk, and it was a bit awkward to have to climb the stairs to use the bathroom; but I was staying in the cheapest room, so I understand (most rooms have private restrooms).
I enjoyed my stay here and I'd love to come back in the future
