We went over there by car which is more complicated. In case you are doing the same try to avoid the rush hours (if you are not used to that traffic). There is no garage available, however parking close to the appartment is possible and for free. We got the best introduction by Joao ever... :-) He explained us the main parts of Porto and always had a recommendation for all over questions. Communication was just perfect. Average response time < 5 minutes :-) The appartment is really nice and clean. The view over the river is just beautiful. All attractions are within walking distance. Totally recommend the accomodation and do not forget to take a port wine tour over there...
