very nice suite, super clean, very functional and great design. Keypad only doors are brilliant! (glass door keypad is the black square over the handle). Small note, bathroom is super slippery as soon as any water is on the floor -make sure you have a towel down or wear shoes. As others mentioned the balcony/window goes towards a shaft so no view but it makes the space quiet even when the windows are open.
The location is good if you want to be near Riberia (old centre of the city) but not really central to modern Porto-I would probably chose a different location next time. .. The road the apartment looks a bit run-down (dark and a lot of buildings are boarded up) but plenty of people during the day and I never felt unsafe (even at 3am for my taxi pickup).
