The apartment is ideally located - you can walk to everything in the city from there, and there is a metro station very close for when you arrive from the airport. Carlos was an excellent host, giving me tips about what to see and where to eat (including vegetarian places!), making me feel at home and letting me leave my bag there on the last day until my flight. The room is lovely and great value for money. I will definitely come back if I am in Porto again!!
