The apartment, on Rue de Faria Guimarae, is slightly outside the main tourist area of Ribeiro but is probably all the better for that. It is well within walking distance of that area and the main tourist attractions. There is a metro stop just a short walk down the street from the apartment (Yellow Line D) which takes you to the main metro hub, Trinidade. We found, however, that Porto is a very walkable city and we really only used the metro for the airport trips. Be warned, though, Porto is hilly so it will test your fitness!!
Rua de Guimarae is a very busy traffic street-it seems to be a route out to a motorway- but, having said that, the apartment was quiet and very comfortable. There are shops, restaurants and cafes in the streets close by. A corner greengrocer just up the street was very handy. If you feel like someone else preparing your breakfast there is a little cafe just opposite.
We had a very enjoyable two weeks there.
