Inocencio is a great host. He gave us a lot of tips on what to do in Porto. His apartment is located on a great location. The metro takes about 5/10 minutes to arrive in the city center. You can also walk, this will take about 30 minutes. We travelled by car. 5 minutes walking from Inocencio's apartment is a parking garage Casa da musica, which was not expensive. 3 days for 40 euro's. We booked it in advance. We recommend Inocencio's apartment if you're going to Porto.
