The apartment is extremely well equipped, even for a longer stay (although we stayed only a few nights). It has a view in the back of the building, which is very quiet, but is within walking distance of good restaurants in the old town. Another plus is that the bed was extremely comfortable. In addition, it had nice decorations (including photos of Porto). The only minor downside is that for the check-in you have tongo and pick up the keys from a different place until a certain time, so make sure you don't arrive very late or you have to pay the fee. This was not an issue for us, so we were very happy with the place.
