João is a great host. Even though we arrived very late he was right there to greet us, sit down and get a ton of great recommendations, really useful when coming to a new town. The place itself is incredibly well located, right smack in the center of town, but still on a side street so you don't wake up with the morning rush hour traffic of a boulevard. Most of Porto's landmarks are within walking distance, you are located strategically half way between the upper part and the Ribeira, which means that we only used transportation to get to and from the airport and to a surfing beach João recommended. All in all, a definite recommendation for João personally and for his apartment.
