We really enjoyed our stay at this place. The apartment is nicely decorated and has everything needed for a short stay. We were received personally and got lots of tips on sightseeing, local food and good places to visit. It was also a nice gesture of the owner to give us a bottle of local wine and a fruit bowl as a welcome! The next subway station is just around the corner, but it is also possible to walk to the city center (on the way back, you'll have to go uphill though). There is a private parking space included, it is inside the courtyard, so it is safe to park there. We could do everything on foot in Porto.
