We had a great stay at Marco’s place; and we were very well received by Cassilda who gave us lots of great tips and recommendations. The apartment was absolutely perfect, well-located and a few minutes walking from all the touristic and must-see spots in Porto. There is also a convenient parking space: the “Parque De Estacionamento Central“, Cassilda has discount vouchers, which gave us a 7€/day price, which was a great deal! (We had also tried previously to park our car at the “ Estacionamento Praça dos Poveiros” parking as other people has recommended in the comments, but upon arrival we were told that all of the 72h/20€ slots were sold out, so watch out if you go there!)
The apartment is spacious, clean and has everything you might need! The WiFi works very well, and we were provided with extra blankets and a couple of electrical heating units if necessary. The shower was also great, lots of hot water; and the place was overall very well decorated in a classic and colourful style. Would recommend 100%!
