We had a fantastic time in Porto thanks to Maria and Sergio's hospitality! The apartment is very cute and clean with a fantastic view of the river. The AC in the bedroom was also a plus if you're there in the summer, plus thoughtful touches like a bottle of wine and water in the fridge when we arrived. Note that the river location means you'll have to climb every time you want to get to the historic city center where most of the sites are, but that is Porto! Very relaxing and peaceful apartment; would definitely recommend and stay here again.
